My sister and I are trying to install old games to her computer. Unfortunately, every time we try to install games such as Sims 1 and Caesar 3, both games' setup.exe won't load at all. The computer acts busy but the installation setup won't load no matter how long we wait. We tried many times like running as admin and playing it for XP in compatability mode but still no luck. We're installing it in Windows 7 Ultimate. Both games install and work well in Vista, however.
