COM Add-Ins for Excel Student Edition

Hi Everyone,

A colleague recently wrote a COM Add-In for me which reads share information from a TXT file and places it into selected cells in my worksheet. This is on a PC running:
- Win7 x64 Ultimate
- Microsoft Office 2010 Professional x64
Everything works perfectly.

I tried to share this COM add-in with a friend who runs the following system:
- Win7 x64 Home Premium
- Microsoft Office Home and Student 2010
However, I cannot, for some unknown reason, get the Add-In to display as shown in the attached image. All I get is a blank despite trying to add, and browsing to the correct file location.

I have tried this several times now, as administrator, and after closing and reopening Excel. The PC is a very recent build (2 days ago). I've exhausted all my knowledge.

Am I missing something? Is there a limitation to COM Add-Ins in Microsoft Home and Student 2010?

Thnaks,
Golden

I eventually found the solution to the problem : UAC has to be turned OFF to get the Automation Add-In to install.
