I had a look at the reference link above by ice_pdb and could not find a definative answer.
From looking at the TRACKIR website the unit will work with version 10. That is the good news.
If you have a look at the manual for the latest version of the software, under Section 3 the minimum system requirement is Windows Vista or later. That is the bad news. The link to the manual is https://www.naturalpoint.com/trackir/documents/TrackIR-software-5_4_0-Manual.pdf
Unless somebody else can correct me then that is the bad news.
Hope this helps.
