I'm getting the following error:

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module.

Additional information: Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

Does anyone know what is causing this error? I get this error when I try to run my project and I haven't done anything at all to make the System.Windows.Forms.dll file disappear. I also deleted the reference and added it again to the project but that hasn't fixed the problem. Any other ideas?

Hi cheatcountry,

What kind of project did you develop? Does it throw out the error before the "Application.Run" is called? Which version of VS and .NET Framework did you use?

Sincerely,
Kira Qian
