I have a PFCcirrus 2 flight simulator and have been running prepar3d successfully. I downloaded v4 of prepar3d. As I had difficulty in getting the throttle quadrant and radio stack to work I arranged with a PFC technician to access my computer. He loaded the throttle quadrant but stated that I needed a driver from you to activate the radio stack. I have purchased and loaded FSUIPC5. Could you please advise me if I need a driver and if so where can I find it.Many thanks David McMullan

This is the 64-bit version. Please see the History document installed for you in the FSUIPC Documents folder for details of the changes since the very first release, 5.10.
