Thanks to Whs for suggesting that I open this thread.
After installing windows vista SP1 on 4-08-08 on my home basic laptop, I've gotten error message on several websites when trying to install software: "Windows installer service could not be accessed." At some websites I have been able to install software with no problems. I have checked microsoft support site and have done live searches and have found no solutions.
I would appreciate your help. Thanks.
