SUMMARY

This article describes how to troubleshoot setup problems with Visual C++, 32-bit Edition, in Windows NT. Because most developers are more familiar with troubleshooting 16-bit problems, this article also mentions 16-bit methods that do not carry over to 32-bit setup troubleshooting.

Slight differences in a Visual C++ 5.0 or 4.0 setup versus Visual C++ 2.0 setup (such as the presence of an uninstall program) are noted here.

MORE INFORMATION

The majority of 32-bit setup problems can be broken down into two areas:

  • Hardware failures, problems, or incompatibilities.


-or-

  • Bad or Corrupt installations.

Each area is discussed in detail later in this article.

Use the following general process to troubleshoot Visual C++ setup problems in Windows NT:

  1. If you receive an error message from the setup program or some other component of Visual C++, try to search the Microsoft Knowledge Base for a list of known problems by using words from that error message. The Microsoft Knowledge Base (KB) is available on the services listed in the "References" section at the end of this article.


The KB is a dynamic collection of articles. Significant new articles and updated information is added daily. A snap shot of the Visual C++ 4.0 Knowledge Base is available on the product CD-ROM compact disc itself through the integrated development environment.

  1. After running setup, if Visual C++ will not run at all, test the hardware first by using ideas from the "Hardware Failures, Problems, or Incompatibilities" section of this article. Then try using ideas from the "Bad Software Installation" section of this article if necessary.
  2. If Visual C++ starts but does not work correctly, first test the installation using the information in the "Bad Software Installation" section of this article. Then try the "Hardware Failures, Problems, or Incompatibilities" section of this article if necessary.

HARDWARE FAILURES, PROBLEMS, OR INCOMPATIBILITIES

The problems you're experiencing may also show up in other applications. However, even if you are not having trouble with other CD-ROM-based applications, that does not necessarily mean that you won't have one of the problem discussed in this section.

First, check the Event Log with the Event Log Viewer application located in the Administrative Tools program group. The Event Log records a number of actions that your Windows NT system performs, including many hardware and software failures. Bad events are usually shown by a stop sign icon on the right side of the list. By default, the list is sorted by date.

If you see a number of stop signs for the same service or device, that sometimes indicates a hardware problem. Double-click the events to see if they all hold the same or related messages that indicate hardware device failures. Note, however, that even if there are no stop signs in the Event List, you may still have a hardware problem that was not detected by Windows NT.

Step-by-Step Troubleshooting Process

Failures of the CD-ROM drive or hard disk system are the most frequently encountered cause of setup problems. Check for possible causes in this order:

  1. Check for a bad SCSI termination. Most SCSI drives require a SCSI bus terminator on the end of the SCSI cable. Event Log time-out events or a number of the same type of failures from the SCSI or disk drive device can be an indication that the SCSI bus has a missing or incorrect termination resistor.
  2. Check to see if your hardware is on the Hardware Compatibility List (HCL). The HCL can be found in Help file format in the Support directory of the Windows NT distribution disk. Make sure all hardware drivers are correct and compatible with Windows NT. Check the HCL for your machine manufacturer, your hard disk maker, and your CD-ROM manufacturer. A number of IDE drives have been known to cause problems in Windows NT. Check the HCL or your dealer for the components in question. Microsoft specifically tested Windows NT with the devices on the HCL list, so hardware on the list is known to function correctly under Windows NT.

    Contacting the device controller manufacturer for updated drivers and/or firmware is always a good idea when incompatibilities are found, even for hardware not on the HCL list.

    You may also have other driver problems that only show up because of memory conflicts with the CD-ROM driver or some other driver. Windows NT is a symmetric multiprocessor operating system that can take advantage of multiple CPUs. Some drivers are not designed to run on multiprocessor computers. If you have a computer with more than one processor, check with the driver's manufacturer to be sure it will function properly. Visual C++ and the Visual C++ setup do not have any known problems running on multiprocessor machines.

    You may also have loaded the wrong driver when you installed Windows NT. If Windows NT did not automatically detect the hardware on your machine, make sure you loaded the right drivers for your hardware.
  3. Check for bad sectors on your hard disk. Run Chkdsk from within a Windows NT MS-DOS command prompt. If you find errors, fix them with Chkdsk /f. To check for a media surface problem, use Chkdsk /r to do a surface scan of the drive in question.

    You may receive a message stating that the volume cannot be scanned because it is currently in use. Answer Yes to the question of whether you would like to schedule this drive for checking on the next system startup. In this case, Windows NT will perform the check and/or fix the next time you reboot. Shut down and restart the system to allow the check to occur.

    These commands check the integrity of the file system and check the hard disk surface itself for physical defects that may cause data loss. Chkdsk /r is the equivalent of the using the MS-DOS Scandisk program. Scandisk will not run under Windows NT or on an NTFS or HPFS drive while the machine is booted into MS-DOS.

    NOTE: This operation can take some time depending on the size of your hard disk.
  4. Check for corrupted files on the hard disk. These problems are often caused by the problems listed in steps 1 through 3. However, corrupted files can also be caused by CD-ROM or hard disk drivers when the files are created during the CD-ROM to hard drive copying process. This corruption usually shows up when setup runs without errors but some component of Visual C++ will not run.

    For more complete information on troubleshooting CD-ROM problems in Windows or Windows NT, please see the following articles in the Microsoft Knowledge Base:

    94653 Using FC.EXE to Verify CD-ROM File System Drivers

    126380 Troubleshooting CD-ROM Problems in Windows NT

    Use the MS-DOS or Windows NT File Compare program (Fc.exe) to compare the files that have been copied from your CD-ROM drive to your hard drive as follows:

    FC /b [drive1:][path1]filename1 [drive2:][path2]filename2

    The /B (binary) switch tells the File Compare program to run a binary compare on the files. Comparing the files in the Bin subdirectory of the Visual C++ installation (\Msvc20\Bin or \MSDEV\BIN by default) with the Corresponding directory on the CD-ROM disc will generally tell you fairly quickly if you have a problem.

    Note that the Visual C++ version 5.0 installation binds most of the EXEs and DLLs for address fix up to achieve a faster startup of the Developer Studio shell. For this reason, file compare cannot be used to check for corrupted files in version 5.0.

    NOTE: There are two files (Msvcshl.dll and Spyxx.exe) in the Bin subdirectory that FC.exe will report as different. These two files are modified as part of the installation process, and are therefore expected to be different.

    If no errors are found in the Bin directory, check the entire Visual C++ installation using Fc.exe if Visual C++ still won't run.

    If Fc.exe reports differences, be sure you have checked the problems listed in steps 1 through 3. If these do not apply, your CD-ROM driver is likely the cause. You have three choices at this point:

    1. To be absolutely sure, delete the Visual C++ directory on your hard drive and reinstall. Then use Fc.exe to check the installation again. If you still receive a report of differences try one of the following two choices.
    2. If there are only a few corrupted files, use the Xcopy command to copy the files from the CD-ROM disc to the destination location. Use the Fc.exe command to compare the files again.
    3. If you can, transfer the entire Msvc20 directory tree to a another installation location. If you are on a network and have sufficient hard drive space, use another computer with a working CD-ROM drive to copy the Msvc20 tree to the hard drive. Then share out the hard drive, and try to install the product from there. Use Xcopy /s to copy the Msvc20 tree from the CD-ROM disc to your hard drive. Type Xcopy /? at Windows NT command prompt for more information on using Xcopy. The directories for version 4.0 is MSDEV, and the directory for 5.0 is DEVSTUDIO. It may be advisable to copy the whole CD image instead because, there are other components which are installed for these two versions.

      Alternatively, you can share out the CD-ROM drive on the other machine and install from there.

      NOTE: You cannot install using a UNC connection with versions before Visual C++ 4.0.. You must connect to the hard drive using a NET USE command/File Manager/Explorer. For more information, please see the following article in the Microsoft Knowledge Base:

      115327 FIX: SETUP.EXE Cannot Start via a UNC Connection

  5. Check for a bad CD-ROM compact disc. This is unlikely yet still possible. Verify that the CD-ROM compact disc is bad by doing one of the following:

    • Wipe the CD-ROM disc gently with a soft cloth to remove any smudges, dust, or fingerprints. Be careful not to scratch it. Wiping outward from the center is the recommended method for cleaning a CD-ROM disc. Any scratches produced will be radial and less likely to affect data transfers. Inspect the CD-ROM disc for deep scratches. These can also cause read errors. Often these errors will show up in the Event Log as read errors from the disk drive device.

      -or-
    • If another machine with a different CD-ROM drive is available, install on that machine, and see if the installation works. If it does, you've verified that your CD-ROM disc is not the problem.

      -or-
    • If you have another Visual C++ CD-ROM disc for the same Visual C++ version, use Fc.exe to compare the two for possible differences. You could also install from this second CD-ROM disc. If everything installs and works, then it is probable that the first one is bad. Call Visual C++ Product Support at the number included in your documentation that comes with the product. Be sure to be prepared to repeat the tests that led you to the conclusion that your CD-ROM disc was bad.

BAD SOFTWARE INSTALLATION

Step-by-Step Troubleshooting Process

  1. Check the Microsoft Knowledge Base for known problems before troubleshooting a problem that Microsoft has already tracked for you. The Microsoft Knowledge Base is available on the services listed in the "References" section at the end of this article.

  2. Check for Visual C++ corrupted Registry entries. If you are not familiar with the Registry, be very careful following these instructions. Deleting the wrong registry keys can cause many more problems.

    Registry entries may be viewed or edited by using Regedt32.exe, which comes with Windows NT. The registry is a database designed to hold information about your entire Windows NT system. Visual C++ and other Microsoft applications store configuration information in this area. For version 2.0, you will find this information in the following key:

          HKEY_CURRENT_USER\Software\Microsoft\Visual C++ 2.0

    The 2.1 and 2.2 updates still use this key. A new registry entry with all default values is generated the first time you run Visual C++ if there is no registry entry for it.

    For you to see this information, HKEY_CURRENT_USER must be the window in focus. The other keys (Software, Microsoft, and so on) are contained in a tree structure similar to the directory structure shown in File Manager. You can select a registry key by using the mouse. Double-click the key to open up any other branches below it.

    Visual C++ version 4.0 uses the following registry keys:

          HKEY_CURRENT_USER\Software\Microsoft\InfoViewer
      HKEY_LOCAL_MACHINE\Software\Microsoft\Developer
      HKEY_LOCAL_MACHINE\Software\Microsoft\InfoViewer

    For the standard version of 4.0, the registry keys are:

          HKEY_CURRENT_USER\Software\Microsoft\DeveloperStd
      HKEY_CURRENT_USER\Software\Microsoft\InfoViewer
      HKEY_LOCAL_MACHINE\Software\Microsoft\DeveloperStd
      HKEY_LOCAL_MACHINE\Software\Microsoft\InfoViewer

    For version 5.0, the registry keys are:

          HKEY_CURRENT_USER\Software\Microsoft\DevStudio\5.0
      HKEY_LOCAL_MACHINE\Software\Microsoft\DevStudio\5.0
      HKEY_CURRENT_USER\Software\Microsoft\InfoViewer\5.0
      HKEY_LOCAL_MACHINE\Software\Microsoft\ InfoViewer\5.0

    Other developer packages also use this these registry keys, so deleting the entire key may make other developer applications nonfunctional. It is best to use the Visual C++ uninstall program to remove version 4.0 and 5.0 installation and registry information.

    Other developer packages also use this registry key, so deleting the entire key may make other developer applications nonfunctional. It best to use the Visual C++ uninstall program to remove version 4.0 installation and registry information.

    NOTE: Before trying this step, be certain that you have the correct key selected (highlighted). If you delete another key, you may destroy valuable information that your system or another application needs to run.

    You can delete the Visual C++ registry tree by selecting it and then clicking Delete on the menu. When this key is removed, Visual C++ can still be run, but it may not have some of its parameters set properly.

    Running parts of the Visual C++ interface may restore some of the registry keys to their default values, but rerunning setup is the only way to fully restore the registry. If you just need the registry entries and/or program groups regenerated, it's best to run the 32-bit setup in the Msvc20 directory on the Visual C++ CD-ROM disc with the /F option. Running the global setup in the root directory of the CD-ROM disc will not pass the /F option on to any other spawned setups. The /F option is useful because the icon groups and registry entries are recreated but no files are actually be copied to the hard drive. Be careful to chose the same options that you chose when you did the original file copy installation, or Visual C++ may not work correctly. Go to the MSDEV directory for version 4.0 and the DEVSTUDIO directory for version 5.0.

    If the problem is not fixed by deleting just the registry entries, the next easiest step is to delete the entire Msvc20 or MSDEV or DEVSTUDIO directory tree and also delete the Visual C++ registry Key as noted above. Reinstall Visual C++ and test the installation again.

    Again, in Visual C++ 4.0 and 5.0, use the unistall feature to remove registry entries.

  3. Check for other corrupted Registry entries. To test this possibility, create a new user account by clicking New User on the User Menu in the User Manager application; User Manager is usually in the Administrative Tools group icon. Then install Visual C++ when the new user is logged in. You can use setup with the /F option, but keep the limitations described previously in mind.

    If the software installs or runs correctly on the new account, the problem is most likely caused by bad registry entries on the old account. If the problem persists on the new account, the registry is probably not a factor.
  4. Check for other bugs or problems with setup. Search using vc20setup, vc40setup, or vc50setup in the Microsoft Knowledge Base for a list of known issues with the 32-bit Visual C++ setup program. Then read the following section for other possible hints.

OTHER TROUBLESHOOTING INFORMATION

In 16-bit Windows, one of the first strategies to try in diagnosing setup problems is starting the computer in a "clean boot" configuration, which means all unnecessary commands are removed from the Config.sys and Autoexec.bat files.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:

During system startup, Windows NT adds any Path, Prompt, and Set commands from the C:\Autoexec.bat file to the Windows NT environment variables, and then ignores the rest of the contents of C:\Autoexec.bat and C:\Config.sys. If these files are not present when you install Windows NT, the Setup program creates them. For a RISC-based computer, default Autoexec.nt and Config.nt files are created. The path and other Windows NT environment information are stored under the following Registry key: 

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
       \Control\Session Manager\Environment

When an MS-DOS-based application is started, Windows NT executes files specified in the application's .pif files or the Autoexec.nt and Config.nt files in the SystemRoot\System32 directory. Any changes made in one of these files take effect as soon as the file is saved and a new MS-DOS-based application is started that uses that file. You do not need to restart your system after changing the *.nt files.

                             can be created and used when starting an
                             application from another .pif file.)

You can use Windows NT Diagnostics to view the contents of the Autoexec.nt files and the Config.nt files by clicking items on the File menu. You can edit the contents of these files by using any text editor.

Commands in the Autoexec.bat and Config.sys files for starting applications and initializing drivers are ignored in Windows NT.

It's important to note that different settings are used for MS-DOS-based and 32-bit console applications. Cl.exe and Link.exe are 32-bit DOS-extended applications, which means they load and run under Windows NT as native (console) applications. Currently, the only MS-DOS process invoked by the 32-bit edition of Visual C++ is the resource compiler (Rc.exe).

For information on the Command Prompts and the four configuration files mentioned previously, please see the following articles in the Windows NT portion of the Microsoft Knowledge Base:

99279 MS-DOS-Based Applications and Command Prompts

124551 Configuring Parsing of the AUTOEXEC.BAT File



Note that the information that used to be stored in the Win.ini and System.ini files has been replaced by registry entries, so making modifications to these files will not affect Windows NT itself. However, many 16-bit applications, including Visual C++ version 1.5x, still use System.ini for configuration information.
