Hello,

Do you have visual studio installed in the system? Did your .NET framework installation was successfull? Check in your system if you have System.Windows.Forms.dll. If your Microsoft .NET framework / Microsoft Visual Studio installation is not successful you might hit this issue. Try installing the .NET framework and see if works.

Thanks

Hi,

I have the same problem. Visual Studio 2005 is correctly installed on the machine. Notice that I have installed the framework 3.0. Could it be a reason ?
