I have developed a excel plug-in using add-in-express. The problem is, after installing the add-in its working correctly but after some days in some systems add-in is disappearing automatically or .NET forms are not opening when we click on menus & buttons.
And also when we un-install the add-in , context menu item is still exist.

Please advice.

Best Regards,

Hi Praveen,

I have a bunch of questions for you:

1. Did you check up the disabled items list?

In Excel 2003, see Help | About Microsoft Office Excel, then the "Disabled items" button.

In Excel 2007, press the Office button and choose "Excel Options". Then press "Add-Ins". Find your add-in in the "Disabled Application add-ins" category at the bottom of the list.

2. Is Excel up to date?
3. What version of Excel do you use?
4. Do you have any code in the add-in module constructor?
.NET, Extended MAPI, Windows Phone & RT
