Vista 64-bit/XP pro 64-bit/windows server 200x 64-bit driver - I installed the freecom dvb-t usb stick (digital only) vista 32/64 bit driver from here.. Then I installed the arcsoft totalmedia software from the cd that came with the usb dvb-t stick. Next I installed the vista update for totalmedia, which you can download from here(size is about 20mb)
With windows server 2008 (32/64 bit), make sure to install the feature desktop experience, as this intsalls the required software - windows media player 10.
Other software that worked with this dvb-t usb stick under vista 64-bit was ProgDVB, which can be downloaded from here
If you are having problems downloading the larger file of 20mbs, I have split it into smaller 1.44mb files, which when placed in the same folder can recreate the original setup exe. Recreation is done via running the batch script in that folder. You will need to download all files.
