i tried changing compatability options but it didnt work either.

i got windows 7 64bit sp1, and microsoft .NET 4.0 and 3.5 but not 3.5.1
i cant uppdate to 3.5.1 beacus it says : "You must use "Turn windows features on or off" in the control panel to install or configure microsoft .NET framework 3.5 sp1.

i tried to do that and i unchecked Microsoft .net framework 3.5.1 and nothing happend i also tried it checked but no difference.

then put my brothers microsoft .NET folder from he's pc since i heard on some forums it could fix it aswell but it didnt.

im totally clue-less with this error but it seems to be microsoft . NET's fault thoug im not sure and i hope you guys maybe know what the problem is.

oh i also tried to use the windows repair cd but that didnt help and i cant restore i allready tried that.
