dllregisterserver in iviewers failed

When I try to run Oleview I get an error saying that DllRegisterServer failed for IViewer.dll (sorry I wanted to post a screenshot but I can't until I get 10 reputation =p)

Oleview will run but like the msg says, you can't look at interfaces which is exactly what I want to do.

I found my iviewer.dll and ran regsvr32 on it just fine. So I'm not sure whats up.

Ack, should have done more due diligence. Found this on msdn which explains that you need to run Oleview as admin. Stupid UAC.

I tried it out and running as admin works for me.

You only need to run it the first time as admin. Make sure you open a tlb file though, so it registers IVIEWERS.DLL as COM server into the registry. After that you can run it as a normal user. This is explained in the Windows SDK readme, by the way.
