Outlook add-in manager doesn't enable

[Bandish 555]

I have an application which has a add-in for outlook. The problem is that add-in doesn't get enabled. I disabled all other add-ins from Outlook add-in manager, but still doesn't work. I also tried removing all other add-ins from Outlook add-in manager, but still doesn't work. Any idea on how can i enable this add-in in outlook? Help!

Try to reinstall Outlook. May be that could make it work... Also Add VSTO environmental variable and see what it shows? Also check the loadstatus of the registry key... What does it say?

Try to use managed code debugging and Fusion logging to see what is actually going. As you add-in is failing to load, If it is loading and then there is some problem, you need to go in degugging mode to see what actually is the problem...

Hey guys, thanks for you help! Well my add-in was in the disabled list and as soon as i removed the add-in from the disabled list, it loaded very well... But not there are not problems, I can sometimes not send mail from outlook. Some mails are sent and some stay in outlook...
