Hi, I was wondering if anyone would be able to help me with my big problem. I recently bought a used but referbished computer and after I tried it out and when to download a program, the program once downloaded would not install. The UAC control would come up on some programs then go away after pressing ok then nothing would happen, no installation box, not even in the task manager. I have already tried to install with the compatibility option but still no luck. The only thing that has installed was a system care program only because my friend sent it to me after downloading it from a torrent. Any help would be appreciated.
