In Windows Explorer, navigate to the location where the .NET Framework is typically stored (C:\WINNT\Microsoft.NET\Framework). You are probably using 1.1 or 1.0. There will be a folder for each version of the Framework that you are using.
A Better Way:
Go to your Control Panel then Administrative Tools. you should have 2 icons there. 1 for .NET Framework x.x Configuration and the other for .NET Framework x.x Wizards.
