Yeah. It has to be the same as the version of Windows 7 you installed.
They have never even made a Vista driver for it. So you could try the XP driver if you want.
They're located here
. <<< Use I.E. You'll have to open the .inf and make the line with this - VEN_13F6&DEV_0111
become this instead
then save it.
Right click in the device manager on it. Update driver software. Browse. Let me pick. Have disk. Browse. Now double click on the .inf you edited and hit ok. Then click next and let it install.
It's probably not going to work, but worth a shot.
If you want to see which version of Windows you have, type system information in the start menu search box then hit enter. Look at the system type line.
