I have a manufacturer installed Vista Home Premium on a Toshiba Satellite. At some point last week I tried to uninstall Photoshop CS2 to install the CS3 and noticed that there is no uninstall button in the control panel / uninstall screen. Right click won't work either on CS2 or any other program. I contacted MS and suggested I spoke to Toshiba's CustSup. I did and they instructed me to backup and format - mind you we're talking about a three weeks old machine. Any ideas that are less extreme?
