i accidentally remove all microsoft.net framework. I tried reinstalling microsoft.net framework 1.1 but there is an error. It was stated ' Microsoft.net framework set up failed. if the problem continues, contact product support service'. What should i do now? i have very little knowledge about 'Microsoft.net framework'. Now i can't even run simple program such as 'paint', 'notepad' and 'window media player'. please help. thanks
