SYSTEM REQUIREMENTS
=======
To run Internet Explorer 4.0, your system must meet the following minimum requirements:
- A 486 with a 33 Mhz processor - 8 MB of RAM - 50 MB of available hard-disk space
WARNING: IF YOU ARE RUNNING WINDOWS 98 BUILD 4.00.950B (OSR2)
==========================================
If you are running an earlier version of Internet Explorer 4.0 on Windows 98 build 4.00.950B (OSR2), you MUST uninstall the earlier version of Internet Explorer 4.0 before you install the latest version. Otherwise, your computer will not be able to start properly.
If you have already installed the latest version of Internet Explorer 4.0 without uninstalling the earlier version, you can work around the problem by carrying out the following steps:
1. Go to an MS-DOS prompt, either by starting your computer
from a boot disk or by pressing F8 when the "Starting Windows 98" message appears on your screen.
2. At the MS-DOS prompt in the Windows directory and in the
Windows\System directory, type the following command:
attrib -h *.w96
to display all hidden files that have the .w96 extension.
3. Type the following commands to copy and rename the needed
files. Press ENTER after each command
Copy comctl32.w96 comctl32.dll Copy shell.w96 shell.dll Copy shell32.w96 shell32.dll Copy explorer.w96 explorer.exe
4. When you have finished copying the files, you can delete the
*.w96 files.
5. Restart your computer.
6. In Control Panel, click the Add/Remove Programs icon,
and then follow the directions on your screen to uninstall the earlier version of Internet Explorer 4.0.
SETUP
=
- After you install Internet Explorer 4.0, do not install Windows 98
or Windows 98 version 4.00.950B (OSR2). If you do, the new shell/ Windows Explorer system files will be replaced.
- If you are running an Internet Explorer 4.0 build 1095 or lower
on Windows 98, you need to uninstall the earlier build before you install the latest version of Internet Explorer 4.0.
- If you have to reinstall Windows, you might get messages saying that
Windows Setup has encountered a conflict and is trying to overwrite a newer file. If this occurs, always answer No, that you do not want to keep the existing file. Otherwise, your computer might not start properly.
Installing Personal Web Server
If you already have an earlier version of Personal Web Server installed on your computer, you must carry out the following steps to install the latest version:
1. Uninstall Personal Web Server by clicking the Add/Remove
Programs icon in Control Panel.
If you don't see an entry for Personal Web Server, you can uninstall it by carrying out the procedure outlined in the topic "Uninstalling Personal Web Server" later in this document).
2. Move any content files and folders you have created in the
following locations to a backup location:
Program Files\Personal Web Server\Wwwroot Program Files\Personal Web Server\Scripts
3. Delete the Program Files\Personal Web Server folder. This
step makes sure there are no folder renaming problems that could prevent the latest Personal Web Server files from being installed correctly.
4. Install the latest Internet Explorer 4.0 Personal Web Server
from the add-on page. If you get a file version conflict message while Personal Web Server is being installed, click Yes to install the newest files.
5. Restart your computer so the changes can take effect.
6. Move your backed-up content files to the following folders
under the Webshare folder that is created on the root of your hard disk when you install Personal Web Server:
For files you want shared over HTTP, copy to:
Webshare\Wwwroot
For files you want shared over FTP, copy to:
Webshare\Ftproot
Installing on a Dual-Boot Computer
If you install multiple instances of Internet Explorer 4.0 on different platforms on the same computer, you must install each instance into a unique directory. Do not accept the default directory for both installations, otherwise uninstall will not work properly.
Running on Windows NT
This version of Internet Explorer 4.0 works only on the released version of Windows NT 4.0 (build 1381). It does not work on any beta build of Windows NT 4.0.
NOTE: You must have administrative privileges to install and uninstall
this program on Windows NT. This includes having administrative
privileges the first time you start your computer after installing
or uninstalling.
You must restart your computer after installing Internet Explorer 4.0. This is also true for some add-on components. You will be prompted to restart, but it will not happen automatically.
Uninstalling Internet Explorer 4.0
You can uninstall Internet Explorer 4.0 by carrying out the following steps:
1. In Control Panel, click the Add/Remove Programs icon. 2. Click each Internet Explorer add-on program to uninstall
it.
2. Click Microsoft Internet Explorer 4.0 to uninstall it.
If you have installed multiple versions of Internet Explorer 4.0 on top of each other, uninstall is not supported.
Uninstalling Personal Web Server
If you need to uninstall Personal Web Server, carry out the following procedure.
1. In Control Panel, click the Network icon. 2. In the list of installed network components, click Personal Web
Server.
3. Click Remove, and then click OK.
Note to America Online Users
When Internet Explorer 4.0 is downloaded (either IE4W95.exe or IE4NT.exe), as with any .exe file that is downloaded through AOL, you will see a dialog box prompting you to set up the download file with an application. Click No, so you can save the file to disk. After saving the downloaded file, you can run the .exe file locally. If you subscribe to another Internet service provider, you can use Internet Explorer 4.0 to access the Internet.
You will not be able to download the Internet Explorer add-on components through AOL. To get the add-on page for proper downloading, you must use Internet Explorer 4.0.
OVERVIEW OF THE CACHE STRUCTURE
===================
With the latest release of Internet Explorer and the Internet SDK, it is expected that many different programs will take advantage of the caching support provided. This means that there could be thousands of URLs downloaded and kept in the cache.
Having thousands of URLs cached into a single directory causes performance to degrade on computers running Windows 98, which uses the FAT file system. There are two primary reasons:
- There is a linear search algorithm in FAT to look up a directory
entry.
- The in-memory structure of the directory entry caching used by
FAT does not work by directory but by individual file, causing it to access the disk more often.
This is the main reason there are multiple directories in the cache. Internet Explorer directs each URL into one of the multiple directories (buckets), where the downloaded data is kept in the form of a file. An index entry is created in the index file(s) in that directory.
For more information about caching or how to use Internet Explorer, click the Help menu in Internet Explorer.
KNOWN ISSUES
==
Running MSN Causes GP Fault
When you run MSN and then close it, you will get a GP fault. This problem will be fixed in a future release.
Making the Desktop Content Active When Not Using a Proxy
If you connect to the Internet over a proxy server, the Active Desktop content is already live.
If you do not connect to the Internet over a proxy server, the Active Desktop appears as local static pages instead of as live content. To make the desktop active, carry out the following steps:
1. Connect to the Internet (for example, by using Dial-Up Networking.) 2. In the desktop news area, click Go Online.
ActiveMovie Shortcuts Don't Work
The ActiveMovie shortcuts on the Start menu do not work. To work around this problem, you can create your own shortcuts on the desktop or on the Start menu.
To create your own shortcuts, use the following paths:
ActiveMovie File Types: C:\Windows\System\ActMovie.exe Active Movie Control: C:\Windows\RunDll32.exe AMovie.ocx,RunDll
Some ActiveX Controls Don't Work on Windows NT
Some ActiveX Controls, such as Citrix WinFrame Client, might not work on Windows NT. There is no known workaround for this problem.
Installing Office 95 on a Windows NT Computer
If you install Office 95 on a computer that is running Windows NT and Internet Explorer 4.0, your computer will not restart properly. You must uninstall both programs, reinstall Office, and then reinstall Internet Explorer. You may need to restart your computer several times to do this.
Viewing Links from Within MSN
If you are trying to view Web links from within MSN(TM), you must change the Options setting on the View menu to browse folders using a separate window for each folder. This will be corrected in a future version.
Line Up Icons and Auto-Arrange Icons Context Menu Items Do Not Work in Web View
In this release, the Line Up Icons and Auto-Arrange commands do not work when you access them by right-clicking inside a folder. These commands work properly from the View menu.
Cannot Play QuickTime and MPEG Movies on Windows NT
With this release, you will not be able to play back QuickTime and MPEG movies directly from the Internet on Windows NT 4.0, but local playback of movie files from your hard disk should function correctly. Playback from the Internet should work correctly on Windows 98.
Time Zones Display Differently
When you use programs that use the java.util.Date class, note that time zones are displayed differently when using Sun's JDK and Java(TM) Support for Internet Explorer 3.0 or 4.0.
For the same entry, the displays would appear as follows:
Sun JDK:
Wed Dec 20 08:57:00 PST 1995
Java Support for Internet Explorer 3.0/4.0:
Wed Dec 20 08:57:00 Pacific Standard Time 1995
This issue will be addressed in a future release.
The Java Virtual Machine is based in part on the work of the Independent JPEG Group.
Netscape Navigator Plug-ins Might Not Work
Some Netscape Navigator plug-ins might not install correctly if Netscape is not present. Internet Explorer 4.0 supports Netscape Navigator plug-ins, but some plug-ins rely on finding the Netscape executable file (Netscape.exe) or locating Netscape- specific entries in the registry. The following are examples of plug-ins that might not install correctly:
- Astound Web Player (http://www.golddisk.com/awp/index.html) - Corel CMX Viewer (http://www.corel.com/corelcmx/) - SoftSource DWG/DXF (http://www.softsource.com) - Autodesk Whip
(http://www.autodesk.com/products/autocad/whip/readme.htm)
Microsoft is working with the vendors to correct this issue. In the meantime, you can work around this issue in several ways:
1. Contact the plug-in vendor to see if they have an ActiveX(TM)
control version for the plug-in. If Internet Explorer encounters an <EMBED> tag for which no Netscape plug-in is present, it searches for and uses an appropriate ActiveX control if one is installed.
2. Some companies offer their plug-ins as stand-alone .dll
files (instead of as auto-installation .exe files). You can download and copy these .dll files directly to the Internet Explorer plug-ins folder--usually at the following location:
C:\Program Files\Microsoft Internet\Plugins
3. Keep Netscape Navigator installed on your computer until
you have downloaded and installed all the plug-ins you want to use.
Uninstalling Netscape after Installing Internet Explorer
If you install Internet Explorer on a computer that is already running a version of Netscape prior to the release of Netscape Navigator 3.0, and then you uninstall Netscape, Internet Explorer does not work properly. To work around this problem, carry out the following steps:
1. In a Windows Explorer window, click the View menu, and then
click Options.
2. On the File Types tab, click Show All Files. 3. Open the \Windows\Sysbckup folder. 4. Right-click the file Url.dll, and then click Copy. 5. Open the Windows\System folder. 6. Right-click in an empty area of the window, and then
click Paste.
Running WebCommander
If you run WebCommander, it installs Internet Explorer 2.0 by default. If you are also running Internet Explorer 4.0, note that WebCommander places shortcuts to Internet Explorer 2.0 on the desktop that look like shortcuts to Internet Explorer 4.0.
Using Novell NetWare 32-bit Client
If you are using the Novell NetWare 32-bit client as your network client, you will need to use the Microsoft NetWare Client to be able to connect to sites other than Microsoft. To work around this problem, carry out the following steps.
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 98. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.
1. Add a new Binary value named DontUseDNSLoadBalancing to the
following registry key:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Current Version\ Internet Settings
2. Set the value of the DontUseDNSLoadBalancing value to:
01 00 00 00
If Internet Explorer 4.0 Windows Don't Work Properly
If you recently installed ActiveMovie and you find that Internet Explorer 4.0 is not working properly, restart your computer. The windows should now work correctly.
Some Certifications are Not Valid
In this release, the information contained in some of the certifications (Authenticode[TM] Security Technology) is not valid.
Using the CompuServe Air Mosaic Browser
You cannot connect to the Microsoft Web page by using the CompuServe Air Mosaic Browser included in WinCIM version 2.0.1. The program will GP fault and then shut down. For more information about connecting by using Dial-Up Networking, see Microsoft Knowledge Base article number Q142490.
Updating Smart Favorites
The Update Smart Favorites command does not work if the path to the Web site contains extended characters.
Cannot View Properties by Pressing ALT and Clicking
In this release, you cannot view properties for an item by pressing ALT and clicking. To work around this issue, you can view an item's properties by right-clicking the item and then clicking Properties.
Screen Might Flicker in Web View with 256 Colors
Your screen might flicker if you are in Web view and your monitor is set to display 256 colors. To work around this problem, change the color setting, or click the View menu and turn off Web view. This is a problem on only some systems.
USING A LOCAL AREA NETWORK PROXY OR FIREWALL
================================
If you want to use a proxy or firewall to protect your Local Area Network from being accessed by others on the Internet, carry out the following steps, which set up your computer to gain access to the Internet through a firewall:
1. Run the Internet Connection Wizard:
- Click the Start button, point to Programs, and then point to
Accessories.
- Point to Internet Tools, and then click Get On The Internet.
2. Configure your computer to connect to the Internet by using
TCP/IP on your local area network.
3. When you are prompted for the gateway address, type the
address supplied by your network administrator only if your organization uses gateways for routing information over the network.
NOTE: The gateway computer is not the same as the proxy or
firewall computer that protects your local area network
from the Internet, so do not type your proxy or firewall
address here.
4. Click the Start button, point to Settings, and then click
Control Panel.
5. Click the Internet icon, and then click the Connection
tab.
6. In the Proxy area, selected the Connect To The Internet Through
A Proxy Server check box.
7. Click Change Proxy Settings.
8. In the first text box, type the HTTP server address for the
computer you want to use as the proxy server. In the second text box, type the port number. The following is an example of a proxy server and port number:
http://myproxy.mycompany.com:80
In this example, you would type http://myproxy.mycompany.com in the first text box, and 80 in the second text box.
You can use a different proxy for different types of addresses. However, if you want to use the same proxy for all types of addresses, make sure you select the Use Same Proxy Server For All Addresses check box.
9. In the Exceptions area, click in the text box, and then type the
names of the computers, domains, and ports on the Internet that, when accessed, will not go through the proxy server. Separate each item you type with a semicolon (;). If you do not know what to type here, see your network administrator.
If you do not want to use the proxy for local addresses, make sure you select the Do Not Use Proxy For Local (Intranet) Addresses check box. Local addresses are defined as those where the server name does not have a period (.) in it. For example:
http://internalweb/ is a local address. http://www.microsoft.com/ is not a local address.
For Help on these items, click the ? in the title bar, and then click the item.
10. When you have finished changing settings, click OK.
11. Click OK again to close the Internet properties in Control Panel.
If you are running Internet Explorer, you need to restart your computer so that the new proxy settings can take effect.
USING INTERNET EXPLORER WITH SOCKS PROXY SERVERS
====================================
If you are setting up Internet Explorer with a Socks proxy server, you must set it up separately from other proxy information (for example, HTTP, FTP, or Gopher). In most cases, this means that all other proxy fields should be left blank and the Socks field should contain the address of your Socks proxy server. The only exception is when you are using a Socks proxy and a different proxy (for example, HTTP) on the same connection. If you are having trouble, please contact your network administrator for information about Socks and proxy servers.
USING PROGRESSIVE NETWORKS' REALAUDIO SUPPORT
=================================
Microsoft Internet Explorer includes support for Progressive Networks' RealAudio. This enables you to listen to audio files in real time over a dial-up modem or direct-network Internet connection. To use RealAudio, you must have a Windows 98-supported sound card installed in your computer. RealAudio works best on 486/33 or faster processors.
To try RealAudio, connect to http://www.realaudio.com.
NOTE: RealAudio will not work if your connection is routed through
a proxy or firewall.
USING INTERNET EXPLORER WITH VIRTUAL MEMORY
===============================
Internet Explorer requires you to use virtual memory in order to run properly. To make sure you are using virtual memory:
1. Click the Start button, point to Settings, and then click
Control Panel.
2. Click the System icon, and then click the Performance tab.
3. Click Virtual Memory.
4. If you are specifying virtual memory settings, clear the
Disable Virtual Memory check box. If this check box is selected, Internet Explorer will not run.
TIP: You can set Windows to manage virtual memory for you by
selecting the Let Windows Manage My Virtual Memory check
box.
SITE MAP
==
The file format used for site map is not in the final format. Please watch the Microsoft Web site for an announcement when the new site map format is available.
SCHEDULING AGENT
====
Microsoft Scheduling Agent helps you automate routine tasks for your computer.
The new Scheduling Agent replaces System Agent that was included in Microsoft Plus! If you have Microsoft Plus! installed, your existing tasks will be upgraded to the new format.
- In order to use Scheduling Agent to manage scheduled tasks on
Windows NT from a Windows 98 client computer, you must install some additional networking components on your Windows 98 computer. These components allow Windows 98-to-Windows NT registry access. For more information, see the Windows 98 setup documentation in the section on networking and registry.
UPDATED DIALING RULES
=========
This release includes updated dialing rules for local, long distance, and international calls in several countries. These updates (1) correct problems in the original release of Windows 98 and (2) implement new dialing rules for countries that have changed their dialing rules since the original release of Windows 98.
During Setup, the updated rules are automatically inserted into the [CountryOverrides] section of the Telephon.ini file in the Windows directory.
New Dialing Rules Not Yet in Effect
The update includes dialing rule changes for France, Finland, and Colombia. However, some of these new dialing procedures have not yet actually gone into effect in these countries. (The France and Finland changes go into effect in October 1996). The changes are included now in anticipation of these future changes, because by the time the Spanish, French, and Finnish versions of Internet Explorer 4.0 are released, the changes will have gone into effect.
Reverting to Current Dialing Rules
If you will be testing Internet Explorer 4.0 in France, Finland, or Colombia before the new dialing procedures are in effect, you need to use Notepad (or another text editor) to modify your Telephon.ini file. To do this, carry out the following steps:
1. Make a backup copy of your Telephon.ini file (for example,
Telephon.sav).
2. Open the Telephon.ini file in Notepad (or another text editor). 3. In the [CountryOverrides] section, comment out the line that
corresponds to the country for which you want to revert to the existing dialing procedures. To do this, insert a semicolon (;) at the beginning of the line.
For example, to revert to the current rules for France, insert a semicolon at the beginning of the line that starts with "Country33=" so that it becomes ";Country33=33".
4. Restart your computer.
When the change does go into effect, you can easily enable the new dialing rules by reopening the Telephon.ini file in Notepad and deleting the semicolon.
