Covert to Excel 2010

Hello, I am trying to convert a whole team of over 50 to Excel 2010 from Excel 2003 (Finally haha).

I would like to know if there is a way I can recognize if 2010 exists on a persons computer through a 2003 vba code. My idea is to create a database and link that to an excel file which could recognize if that person has Excel 2010 on their computer. I can then see which users already have it and which don't.

My plan was to send everyone a macro enabled workbook and see if it causes an error when it opens, but if the Excel 2010 application is not the default when opening the file, it would not work.

Would it be best to follow a path in applications and use Environ("username") as the profile code?

Thanks for the help in advance.
