Further details would be helpful. I have installed one of the latest revs of the Elad software in both Windows 8.1 64 bit and Windows 10 Tech Preview 64 bit without issue. I have the FDM-S2 SDR; great little device.
I hadn't thought of that when I did my installs, but that said they went fine while the AV software ran merrily in the background. Odd. But it's a valid issue in some cases and should definitely be part of the troubleshooting process.
Hi cannot wait till i test against my other hf receivers from aor,commradio,cross country wireless,drake,grundig,icom,palstar,sangean,ten tec,winradio but im very happy with the Elad receivers performance.
