Error unregistering (and maybe registering as well) of JTX Custom Step

[CarstenAndersson]

We've created a number of custom steps for Workflow Manager using your sample in C#. The code can build fine and the assembly is registered, but when unregistered it fails. The code for registration is:

 [ComRegisterFunction]
 static void Reg(string regKey)
 {
 JTXUtilities.RegisterJTXCustomStep(regKey);
 }

 [ComUnregisterFunction]
 static void Unreg(string regKey)
 {
 JTXUtilities.UnregisterJTXCustomStep(regKey);
 }

The error is:

I've looked in the Registry and the class id does exists, but I can see the "Implemented Categories" is not there. Shouldn't there be a "JTX Custom Steps" category for this in the registry?

Any help would be greatly appreciated!

Regards

Carsten
