I am updating an older InstallScript project that worked fine in IS 12. So, I opened the project in IS 2008 Professional, tried to rebuild, and it complained about the MFC 6.2 object I had included back in the old IS 12 version of the project.
So, I downloaded the new IS 2008 InstallScript Objects file and installed it. Next, I deleted the old MFC object and added the new MFC 6.2 Runtime object (IS 2008 version) to the desired Feature. Now, when I try to rebuild, I get an error 126, "Unable to load properties for InstallShield Object(s): Initial Install\New MFC 6 Runtime 1".
Since no one has any suggestions, I've decided to solve this by keeping the installer as IS 12 instead of IS 2008. I will just do thorough testing on Vista and hopefully have no problems. I don't need the Windows Logo on this so leaving it as InstallScript will be fine. In the future this product will ship with a Basic MSI installer, but for now there is not time to rewrite the existing installer for this release.
