Excel won't open/launch VSTO AddIn when running in debug mode of Visual Studio 2010

Question

I had previously installed the VS11 beta, and had some issues with my Visual Studio 2010 instance, which you can see here how they were resolved: Excel AddIn Click Once depl

Answer 1

I've found the issue which was not letting me run my project in 'Debug' configuration mode, though it worked in 'Release' mode. At some point, the AddIn, got hard-disabled (not sure if that's the term to use). At that point, trying to re-enable from within Excel doesn't do anything. Within the registry, there is a folder where disabled AddIns are flagged. I deleted all of the keys from this folder except for "(Default)" and now my AddIn works when launching from Visual Studio 2010 in 'Debug' mode.

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Excel\Resiliency\DisabledItems
