I can't seem to get anything to install into C:\ProgramData (CommonAppDataFolder) without Windows 7 virtualizing it to C:\Users\All Users. I'm pretty sure it has to do with file permissions. I've tried having InstallShield give "Full Control" to the group "Users" to the directories C:\ProgramData\ and C:\ProgramData\\ but it's not granting those permissions. Permissions settings work for individual files in that directory but not for those two directories.
Anyway, my real problem is I can't get anything to install into C:\ProgramData (CommonAppDataFolder) without Windows 7 virtualizing it to C:\Users\All Users.
Have you checked whether the virtualization occurs right after installation or only after the program is launched? For after all, if your application doesn't have a proper application manifest it can trigger virtualization also for support files.
