INFO: Windows Installer May Prompt for Install Source if Unavailable

 * }

Q251214

-

The information in this article applies to:


 * Microsoft Windows Installer, versions 1.0, 1.1

-

SUMMARY
The Windows Installer may prompt for the original install source location during an uninstall or a modify operation the first time either option is chosen.

This prompt will occur if all of the following conditions are met:


 * The original .msi package was installed with the 1.0 version of the Windows Installer.
 * The Windows Installer was upgraded to version 1.1.
 * The install source location is not available at the time of the uninstall or modify.

MORE INFORMATION
This behavior is caused by the Windows Installer needing to recache the product's Installer package. The reason for the recaching is that the Windows Installer has changed the registration of the cache location in order to track per user and per machine installations separately. Once the new package is cached, then the uninstall or modify operations should continue and complete successfully.

The cached packages that are used for maintenance mode operations are cached in the %windir%\Installer directory.
