When trying to install Adobe Photoshop CS3 Extended Trial on Windows Vista the installation would start and after a second the window would close and disappear.
Adobe has very little on this issue according to Google. But it's once again blogosphere to the rescue. Non other that Rick Brewster of Paint.NET fame had a problem installing it on Vista x64, but his solution works for me on x32 too.
Solution: drop to command line with administrator privileges and run
It worked for me!
