Microsoft’s .NET Framework is software designed to help PCs connect to one another, and many programs rely on it. If something goes wrong with your .NET installation, you’ll have trouble and you will get a .NET Framework Initialization Error:
To correct this ,ensure that the C:\WINDOWS\Microsoft.NET\Framework (assuming that XP is on the C drive) exists and that it is not empty. If the folder doesn’t exist (or if it’s empty), then install the .NET Framework. Otherwise, open the Registry Editor, and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework.
In the right pane,double-click the (or create a) String entry named InstallRoot. Set its value to C:\WINDOWS\Microsoft.NET\Framework\. Exit the Registry Editor and restart Windows
