I have XP Pro SP2 installed for no reason other than gaming...I banished it to a 20gb ide hard drive, while I let Linux have the nice 160gb SATA drive. When I try installing things...Most anything now.....I get an error...."Interface Not Registered"...Whether it be games or some DVD burning tools that came on a cd with my burner...What's causing this? I tried a couple of those stupid Registry Fixer deals...To no avail. I have no clue how to use Windows....My friends have to help me with it at LAN parties. ^_^. I'm so used to Linux I'm posting this in the Windows section of a Linux Forum...Hehe.
