Hi

I created an Excel Add-in in Visual Studio using C#, and it seems that the Tab Name is not showing.
Disabling and enabling the add-in solves the issue temporarely, but it's not something that I can ask my customers to do...
And if I close Excel I need to do the enable trick all over again, because the name goes away.

I tried:

  • changing the Tab ID, maybe it was to generic, did not work.
  • cleaning the solution and re-building it.
  • adding the install folder to trusted locations in Excel - Trust Center

Am I missing something? Is there something I need to do for the Tab Name to show?

As I open Excel:

After disabling and enabling the addin:

    I do not know how you build your ribbon tab.
    I recommend you using XML code.
    Works any time and you can do it more then creator do.
