I have an ArcGIS 10.0 extension which will no longer install for users who have upgraded to ArcGIS 10.1. Are there a defined set of changes that need to be made in order to upgrade the extension, or is it dependent on extension options, such as the libraries that are called?

Any other comments/advice on moving extensions to 10.1?

The error recieved upon install is: "Error 1001. Unable to get installer types in the C:\...extensionname.dll assembly. --> Unable to load one or more of the requested types. Retrieve the LoadedExceptions property for more information."

Any other comments/advice on moving extensions to 10.1?
