Another way:
1. Verify that the add-in is not disabled in the registry (I presume you install it to HKCU) HKCU->Software->Microsoft->Office->Outlook->Addins->NAME. The LoadBehavior key should be 3. If it is anything else, change it to 3.
2. Start a cmd prompt.
3. type: set VSTO_SUPPRESSDISPLAYALERTS=0
4. Launch Outlook from the command line shell (so that the environment variable is set).
5. During startup, you should get a UI box that pops up with some debug info about why it is failing to load.
6. Copy the error text from that box to the post here so we can help you further.
