ProgramData virtualization

It's not enough to move data stores from Program Files to ProgramData when upgrading applications from XP to Vista/W7. It's also necessary to, in the application installation, set the permissions on those files to read/write for the group "Users". Otherwise, Vista/W7 will silently virtualize those files into shadow copies to the Users folder on a per-user basis.
