All this is in anticipaton of a new desk top system with Windows 7. How do I discover 32bit or 64bit? I don't have the new system yet.
Download both. If the machine is pre-installed, right-click on "my computer", select "properties and it should say on the next screen under "system". Then install the correct version. If you install windows, it should say.
If the driver software comes as an .exe, righ click on it and select "Run as administrator".
That should work.
