Problem debugging Visio Add-in in Studio 2003 with .NET 2 installed

[PeterS]

I have a .NET add-in for Visio that I built using Visual Studio. In the past
I have had no trouble debugging it (until i installed Visual Studio 2005).


I find that I can't run the Add-in from within Visual Studio in order to
debug it. Visio starts up then disappears.
The second time I try to run it I get the message.


Visio experienced a serious error the last time the add-in 'xxx' was
opened. etc


I'm running VS 2003. However, I do have VS 2005 installed.


I found I could get the problem to go away by uninstalling .NET V2. Of
course now the problem is that I can no longer run Studio 2005.

I can report the same problem, except I only installed .Net Framework 2.

Thanx to your post, I have now de-installed that, but currently, I cannot
still get one COM add-in to fire in debug mode, but others are now working.
Thank you!

I'll report any further findings later...
