After installing Arcgis Web Adapter (IIS) for ArcGIS Server 10.1 I get the following error:
"Could not load file or assembply 'ESRI.ArcGIS.ADF.Core, Version=, Culture=neutral, PublicKeyToken=8fc3cc631e44ad86' or one of its dependencies. The system cannot find the file specified.

I would appreciate any help on this issue.
