Hi Austin!, yeyy, it worked, I managed to install the framework-thingy. (Although the shell is full of error messages, is this normal?) Now, the installer tries to throw two additional things on my hard drive: - Adobe Flash Player 10 ActiveX - .NET Framework 2.0 Service Pack 1 Also, it tries to open something called "netsh" in the windows/system32 folder, but fails. The program itself starts now up to a certain point, but only once. A loading screen appears, and then the window opens but remains grey, and after a few seconds it's not responding anymore and needs to be shut down by force. When trying to start it again, I receive "Unknown error (0x2740)". Uhmmmmmmmmm. And now?
