> It appears the keys have to be registered under HKEY_LOCAL_MACHINE (which means installing will require admin rights no matter what). To fix this, you will have to run this command from an administrative command prompt:
c:\windows\microsoft.net\framework64\v4.0.30319\regasm.exe c:\users\{username}\appdata\roaming\rubberduck.install\rubberduck.dll /codebase /tlb
Future releases will not require that step.
