Hi Edgar,
Thanks for the inquiry.
The weatronic software needs the Windows XP operating system to work properly. (see the wbsite at http://www.weatronic-usa.com/index.p...d=33&Itemid=37 )
I suppose that we will also be offering vista some time in the future. I am not aware of the intention to make it backwards compatible. I will pass this desire on to the manufacturer as well.

Thanks,

Gerhard
