I've run into this same problem. With UAC on and not running as an Admin you will not be able to register a DLL. This requires Admin priviliges... there's really no way around this.

Copying to System32 also isn't going to work for the same reason - normal users have no rights there. I would think there's no reason to copy to the SYSTEM32 directory for a COM object anyway.

The best thing to do is to register as part of the main installation.


I'm also struggling with similar problems. I have some components that need special registration using .NET COM Registration and that also doesn't work for the same reason and I can't get the installer I'm using to do it for me.

Another one: My app auto-updates itself by downloading updates and hotswapping itself - that no longer works either since I'm unable to write the update file and then overrwrite the oringal EXE. The only way for now is to force the user to do this manually - download the file, then pop up a dialog with instructions to run in Admin mode.

It sucks, but it makes sense.

Really not a Vista issue since this is would be a typical IT scenario as well with XP...
