.net framework 2 service pack 1 is the minimum required framework for GameEx since the projet was upgraded to visual studio 2008 and the installer has been updated to detect and install this. Id also like to point out that windows 98 and ME are no longer supported. I would have personally supported them still, but the development tools I am using do not allow me to. The minimum supported OS is 2000 SP4 and XP SP 2. Its been this way for a few releases but I had not pointed it out. In addition HTML applications are fixed on windows XP, and favorites now also feature the random preview videos.
In other news - in partnershup with Micosoft I have purchased compenents used in Windows Media Center and full TV support is on the way.
