IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.



SYMPTOMS
When you run a Quiet-mode Internet Explorer 4.01 Service Pack 1 (SP1) Setup on a computer that already has Internet Explorer 4.01 SP1 installed, you receive the following message:

Setup has detected that the newest versions of Internet Explorer components are already installed. To exit Setup without making any changes, click Exit. To reinstall the current version of Internet Explorer, click Reinstall.

When you run a Quiet-mode Internet Explorer 5 Setup on a computer that already has Internet Explorer 5 installed, the installation progress dialog box appears and before anything is installed, Setup abruptly stops, and the installation progress dialog box disappears. You do not receive a message.



RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

You can prevent the message listed above from being displayed by adding a registry value before you run Internet Explorer 4.01 SP1 Setup. Add this value on all the computers on which you want to run a Quiet-mode Setup: Value name: ReinstallFlagQuiet Value type: DWORD Data value: 1 Add the value listed above to the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Active Setup\Jobs
