I wrote an Excel VBA add-in over ten years ago, which uses the old Commandbars to put a menu in Excel's Tools menu (in Excel 2003 and earlier) or in Excel's Add-Ins tab (in Excel 2007 and later). I've never had a problem with the menu appearing, in all versions of Excel from 97 through 2013.
But now a user says Excel Add-Ins menu not appearing for him in Excel 2013. Normally that means the add-in isn't loaded, but in his case the add-in is loaded and working. We know the add-in is loaded and working because the add-in adds user-defined worksheet functions, and those UDFs are working fine for him. But he wants to get to the add-in's menu and can't.
My googling showed that some people are having trouble with the Add-Ins menu in 2013, but I didn't find anything specific to this problem.
Yes, he's tried enabling the Add-Ins tab in Excel Options > Customize the Ribbon.
BTW this is an .xla add-in, not a COM add-in.
Any suggestions?
I have Excel 2010 and had the add-in tab disappear for MrExcel HTML add-in. I tried all types of suggestions - and finally found one that worked for me!
Go to the add-ins folder where you have your add in saved. Right click on the file, and select Properties. At the bottom of the General tab - if it says "Security" - check on the "Unblock" option.
Voila! My add-ins never disappear anymore!
