Store the Add-in in a Trusted Location

The great solution to the missing ribbon is to store the add-in file in a Trusted Location.  A Trusted Location is a folder on your hard drive or server that has been added to the Trusted Locations list in Excel.

You can either move the add-in file to a trusted location or add the add-in file's location to the list of trusted locations. 

How to add a folder to the Trusted Locations list in Excel:

Open the Trusted Locations menu. File>Options>Trust Center>Trust Center Settings>Trusted Locations.

The Trust Center in the Excel Options.

Press the Add new location.

Trusted Locations in the Trust Center.

Select the Browse button.

Selecting a Trusted Location.

Navigate to the folder that contains your add-in file and press OK.

Press OK on the Trust Center Window.

Close Excel and re-open.

The Default Add-Ins Folder Needs to be Trusted

The following path is the default location where add-ins are stored on the computer:

  • C:\Users\your_username\AppData\Roaming\Microsoft\AddIns
  • C:\Users\your_username\AppData\Local


Please be sure to check the Subfolders check box.

If you store add-ins in this default AddIns folder then you will need to add it to the Trusted Locations list.  For most users, it is not trusted by default.
