>I'm using Innosetup to create a Installer routine. It seems to install, yet when I run the program it is missing the VFP runtime. I've tracked down an error in my install script that should solve the problem, but my question is what are the msm's and where should they be installed to? Right now I'm telling the installer to place them in
>DestDir: "{cf}\Microsoft Shared\Merge Modules"; CopyMode: normal
>where {cf} stands for Common Files. should then go into the c:\windows\system instead?

You don't copy MSMs to install them - you need to invoke the Windows Installer to place them properly. Inno is not a Windows Installer based product.

I'd suggest running out to www.installsite.org and doing a little reading on the Windows Installer technology. Products that do not leverage the Windows Installer technology and are not in the managed code arena are in for a rude awakening. But don't believe me, I just clean up the debris after other people's installs crash and burn...
