Workbench not launching - why? (no replies)

I'm using windows7 on asus laptop. My first attempt to start Workbench ended in the following error line:

mysql workbench has encounted a problem could not load file or assembly 'System.Runtime.Remoting, Version=4.0.0.0, Culture=neutral, PublicKeyToken= ...

I just shortend the rest of it. Could somebody help me to get around it?
