问题
I am writing and debugging an Excel VSTO Ribbon addin and it sometimes crashes due to errors in code. When Excel finally decides it's too much and asked me whether I want to permanantly disable it, I ACCIDENTALLY clicked yes.
Now no matter what I do, I cannot get the addin to automatically load on Excel startup. I go to COMs AddIn dialog and set the checkbox; deleted the registry settings manually; cleaned the project in Visual Studio and rebuilt it -- no use.
Where should I configure to make it auto load my VSTO again? Thanks in advance. btw, it's Excel 2010 on my dev machine.

You have made the addin disabled. To enable it back
Select File => Options then choose Add-Ins. In the Manage dropdown choose Disabled items and if your addin is listed there just enable it.
