Hi all!

I'm getting this stack trace when trying to unregister an xll and was wondering if there are some well known issues I should have a look at:

Unloading is not supported very well, and I think it does not work when you use any of the COM features like a Ribbon extension or an RTD server (or any of the async features that use an RTD server).

However, I think that sample used to work, so I'll have to have a look at what is going on, and whether I also see the error you see.
