Excel 2007 Add-ins Tab has disappeared...
 

Hello,
I have been using Excel and its associated add-ins tab for the last year and
a half. Two days ago my add-ins tab disappeared. The add-ins are loaded but
the tab does not appear. I have tried loading, unloading the add-ins. I have
uninstalled Excel and re-installed it. I have spent a little over 18 hours
the last two days trying to sort this out. I have been on tech support with a
variety of level users (most advanced - including development level
individuals). And I still can't get the tab to appear.

My current Excel worksheets that utilize the add-ins still work. But I
cannot modify, nor build new models or worksheets without the ability to see
the add-ins tab.

I may need to rebuild my computer if I can't find a resolution as
essentially my life stops if Excel doesn't work for me.

Any help would be greatly appreciated.

Best regards,

Colin
