@ Kontrollturm and others having probs installing-updating star force. Do you have the UAC (user account control ) running? I had it on and got some warning about star force drivers not being Vista ready, and had the choice to continue or abort.
It seems that you can get into problems if you kill the UAC when you get tired of it asking you if you started this or that app, if so you can click continue
I tried to install Adobe Reader 8.0 with UAC off and got an error stating that the temp folder was either on an disk that was full or on an disk I could not access and that I should check if the disk was write protected, hu:hmm: I than found on Adobe that I should turn on the pesky UAC again and yes, then the install went ok.
Just a thought.....
