Regsvcs error - "Insufficient state to deserialize the object. More information is needed"
While you run Regsvcs you might get a message saying:
An unknown exception occurred during installation:
1: System.Runtime.Serialization.SerializationException - Insufficient state to deserialize the object. More information is needed.
This might occur because the assembly you are trying to register references another assembly that is missing (could be a versioning problem)
You can use Fusion Log Viewer to determine which assembly is missing.
