Force enable XLAM add in Excel 2013 via GPO

We currently have an Excel com add-in that was created in house. We want to force this add-in to stay enabled. The only issue is, it does not have a progid so I cant use the "List of managed add-ins" within GPO. I need to find another way to force enable the addin. We would like to do this via GPO though. Does anyone know how to force an XLAM add-in to always remain enabled? The registry has this add in within HKCU\Software\Microsoft\Office\15\Excel\Options. The registry is showing the following information for the add-in.



Is there any way to force the add in to remain enabled?

One way is to place the addin here:

C:\Program Files (x86)\Microsoft Office 2010\Office14\XLSTART

Note that this is my path, yours depends on version and installation type. So add an XLSTART folder to the folder containing the Excel.exe file and then place the xlam there.

NB: an xlam file is NOT a COM add-in but a normal add-in.

Wow...was it really that easy?! I copied the XLAM to the XLSTART directory and it showed up without  showing in the add-ins. This was exactly what I needed. I cant believe it was that simple. Thank you very much!
