I bought an older IBM IntelliStation, some time ago, which I believe came standard with PC Doctor. Somehow the application has been damaged, so that it does not run, and I need it to diagnose why neither optical drive works. It says my copy is incompatible with Windows 7, and there is no update available, then it stops. Is it possible to get a downloadable version of the original software, or a working version, since I cannot install it from a CD ?
