    invalid class error after SW trial installation

    Thomas Endlich

      Hi,

       

      after the installation of a trial version of SW I tried to open eDrawings software. Unfortunately eDrawings didn't start and I saw an error:
      "Application Exception
      Invalid class"

       

      Here is a screen:

      I am using Windows 7 Professional operating system.


      Anybody knows how can I fix this error?
