Hi guys. Just bought this joystick. Hardware is great, support sucks! Logitech support page has a rubbish file to download and nothing about the joystick, button maps - nothing. The file didn't work for me at all, so I hit the interwebs looking for a solution. A few hours later and after several failed downloads on dodgy fileshare sites, I found a link for a 64 bit driver which has the profiler to allow customization etc... on an old Reddit archive of all places. In case anyone else has the same issue, I thought it best to post the link here as well:

Hope this helps someone and avoids the same frustrations I just endured.
