ArcGIS 10.1 beta (Specific Version set to false) could not load file or assembly

I followed the chapter "Migrating ArcGIS 9.3 Desktop and Engine custom components to ArcGIS 10" when upgrading from 9.3 to ArcGIS 10. The ArcGIS Desktop extension works fine in 10, however, in 10.1 beta I get the following error:

Command line: /e "C:\Program Files (x86)\MyProject\My.Dll"
Registry Capture On.
Registering managed library...
Managed Exception: Could not load file or assembly 'ESRI.ArcGIS.SystemUI, Vers
ion=, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86' or one of its de
pendencies. The system cannot find the file specified.
Registry Capture Off.
Operation Failed

Version specific is set to false and I have checked that the files exist in the GAC on the client machine. I checked the dependencies for SystemUI and they are System and Version. Both exist in the GAC, although Version is not referenced in my project.

Can anyone help?

Many Thanks
