I added a new release to an InstallScript project which is an upgrade of an existing version of an application. The update works like it should, but when I go the Add or Remove programs and try to remove or change the installation, I get an Unhandled Exception dialog with the following message:

Error Number: 0x80040703
Description: Failed to find DLL function: ISRT._IsWow64

Setup will now terminate.

This happens on both Win2K and WinXP machines. I should note the original application install was created with IS DevStudio 9 and the update release using IS 11 Pro. Also

Is there a way to get pass this problem?

Any help is appreciated.

i found the problem. its the UNINSTALL_STRING, which i use in InstallScript of my project.

the UNINSTALL_STRING use the directory with version 9 of IDriver.exe, but my installation needs version 1150 of IDriver.exe. Thats the reason for the errormessage.

But now i have the problem, why is the variable UNINSTALL_STRING wrong ?
(it seems, that the project dont realized the converting from version 9 to version 11.5 of installshield. my project was created with IS 9)
