I've successfully installed and run SpywareBlaster since having Vista, and previously for years with XP. But that is a history. From yesterday it start to play very badly with me. Yesterday I discovered that there is a new SpywareBlaster 4.1 version so I decided to update, usually an easy thing, just a piece of cake. It installed with no problem but then when I tried to run it (spywareblaster.exe), nothing happened. It didn't launch at all. I thought that maybe 4.1 is some kind of dodgy version so I've tried to go back and installed 4.0, which was working before. Surprisingly with the same result, it simply doesn't want to run. I've tried to install it and run it as administrator, tried to do it in Safe Mode, looked for solution on the net and tried some of fixes, still no go, nothing works. Now is even worse because it doesn't even want to install. when I try to install it I'm getting this error message http://img.photobucket.com/albums/v447/lesoneil/Screenshots/SB.jpg Did anyone came across the same problem and found solution? Any help and suggestion welcomed. PS. Just for the record, it's happening with Vista Ultimate SP1.
