You can't guarantee the order in which files in your MSI file will get installed, so you can't be sure that the VC 9 runtime is installed before your COM Dlls try to self-register. So it's not really surprising that at the end of the install it will work (because now all the files are there).
You *can* guarantee the order on Vista and later - the VC 9 runtime definitely *won't* be installed when your VC 9 tries to self-register. Somewhere in the archives here and elsewhere (the Windows Installer Team blog) you'll find remarks on the evil of self-registration, and now you see why. You should extract the COM registration and add it to your setup (Heat.exe). Other solutions that people have used are static links to the C runtime Dlls or making the VC redist a prerequisite to running the install.

We've included the VC9 runtime merge modules in our product.wxs file & it even installs the merge modules. But it fails to self register the COM dlls. Surprisingly if we ignore the failure & complete the installation we are able to register the dll manually (using regsvr32). I've seen some posts where self registration is discouraged but I haven't been able to find a fix. http://n2.nabble.com/DLL-failing-to-register-on-a-SeflRegCost-file-td2395700.html http://blogs.microsoft.co.il/blogs/yanush/archive/2008/09/22/howto-use-regsvr32-exe-with-wix.aspx Already spent a few days to figure out a fix so any help would be appreciated. ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
