Thanks, Tech_Support. I currently have Secure Boot disabled in my BIOS. I suspect most newer machines have it ON by default. I am running W10 Pro x64 version 1511. I will avoid 1607 for a while. I tried testing under VMware Workstation/Player but I could not get SDRPlay to connect. AirSpy does work under SDR#. I am currently trying Hyper-V. When (and if) I get it working I will try 1607 with and without Secure Boot (looks easy to change in Hyper-V). Right now still trying to understand how to boot Generation 2 VM from the DVD to install W10. It looks like DJ2NL (thread
) has a W10 (1607) problem right now.
Thanks and enjoy, John.
EDIT: The only way I could find to get SDRPlay/SDRUno to work under W10 v1607, was to have Secure Boot disabled.
