Fix problem in Outlook 2007 Add-in (does not load)(repost)

Attached Outlook 2007 add-in does not load. The add-in works fine inside the VS 2010 IDE, but it seems there is a problem with the setup, as the add-in seems to fail during load in Outlook (when installed on a separate computer). I can see the following possible problems: - The signature might be for a different Outlook version. - A reference might be missing from the setup. - other Your job: Make it work in the following environments: - XP or Windows 7 - Outlook 2007 To reproduce the problem: - Install the solution - Open Outlook and navigate to add-ins - You can see the add-in as desactivated, if you activate it manually, you can see an error message ## Deliverables There is a warning in the solution. You can ignore that I think. It's because the solution is built upon Framework 4.0 instead of 3.5 and VSTO seems not to know that option. The app connects to a db, which already exists on machines (and therefore is not part of the setup). Just create a folder C:\SIS and place it there. You won't need it, except for the connection, because the app doesn't even get to the point where it makes use of it. Possibly the problem is the loader, and if not, the ThisApp part where the addin is initialized.
