hi,
i have a question about how Windows Installer makes copies in the %windir%\Installer folder.
I use transforms to generate multiple instances of an application. The problem is that when user wants to perform a modify or repair of the application, Windows Installer starts to search for the original MSI which is not always available.
After some research i found out that Windows Installer stores only a small part of the MSI in the %windir%\Installer folder - I guess that this small part is the transform diff.
So i tried to use an embedded transform (at least i think i did), using the MsiDatabaseApplyTransform MSI API function, but the result was the same.
Any ideas on how to force the Installer to cache the whole MSI?
thank,
crush

That guess would be incorrect. The cached MSI is essentially the original but minus internal CABs.

Hey,
thanks for the answer, I came to the same conclusion
And form what I could gather, there is no "elegant" way to cache the whole MSI.
Thanks anyway,
crush
