I believe modern (meaning I don't know which version of Windows started this) Windows systems have a per-user HKCR override. So it is possible to have variations like this.

I know the COM class is registered as I can call it from NUnit tests, a command line app and I even browse to it from IE and I see it respond. Running or debugging the project in VS2013 as Administrator gives CLASSNOTREG (I run as admin because I was using Local IIS). As an experiment I changed to IIS Express and ran as a normal user and it works. Why on earth would a COM class not be found when running VS2013 as admin? Greg K
