I've just (yesterday) completed my Threadripper 3960X build with an ASUS PRIME TRX40-PRO motherboard and can't get AMD Ryzen Master working.
I get the same message as the original poster in this thread, I've updated Windows, updated BIOS for the motherboard and installed the latest AMD Chipset Drivers and reinstalled the software (AMD Ryzen Master) several times.
I'm running a clean install of Windows 10, and even re-installed Windows from scratch once without any success.
I can't find any logs regarding this error message, neither on the hard drive or in the event viewer.
None of the solutions found in this forum and elsewhere seems to be working for me.
