What version of Outlook, what version of VSTO?
Is this deployment to a different computer than the development computer?
Did you set security for the VSTO addin assembly, sign the assembly and make
sure all the pre-requisites are on the target machine (vsto runtime, PIA's,
framework, extensibility.dll, stdole.dll, any other references, possibly the
registry lockdown fix and other fixes)?
Did you look at the installation and deployment walkthroughs (2 part
article) on MSDN? I can't provide a link for them right now, they've been
moved with no forwarding links.

After reading this blog:
http://blogs.msdn.com/mshneer/archive/2006/01/05/deployment_articles.aspx
I think I need those to articles but you're right, the links are dead.
However, the blog entry doesn't give the titles of the articles so I can't
even serach for them. Do you remember what the titles were?
TIA

first one, there's a link to the second one at the bottom of the first

Thanks
OK, I recreated my entire solution from scratch so it has a correct
automatically created setup. The only things I changed were the friendly
name and the description in the setup.
However, I still get "The Managed Add-in Loader failed to initialize."
Any ideas?
TIA
