Hello

I have created a sample add-in using the VS2005 add-in template. When
I register this add-in and try to load in Excel (Tools->Add-ins-
Automation->Select the ProdId) I get a message "xxx is not a valid
Click to expand...
add-in"

What am I missing?

Any help or pointers appreciated...

Thank you for your time

I ran into something like this when developing an Outlook addin. On the
deployment machine, it turned out that Outlook was not allowed to fully shut
down before the addin was installed. This caused it to not be properly
registered (the details of this allude me). After ensuring that it was
shutdown, and running a repair of the installer, all was well.
