Install Win 8.1 is not possible

Installing on my streamer with Win 8.1 pro was not possible. I think because it’s not 64 bit like Win 10. On my laptop with Win10 it worked well. It was a nice experience with a compare of JRiver MC22. JRiver had the best sound and comfort. Audirvana ver.1021 operated not very smooth ( hickups and delay) in my setup. MQA worked perfect. The displayed MQA rate of 352 kHz / 24 bit is the max. rate. On my DAC was displayed the correct rate of 88,2 kHz (1st fold !)
