This support video found at the link below walked me through all the steps to get WMDC to work in Windows10. Once WMDC was operating, my URC MX-980 was recognized and I was able to run the CCP Programming software with no problems! At long last! I hadn't been able to get it to work since WindowsXP.
ALSO: Note that the registry hack utilized during this process (also discussed in the video above) contains a character in the registry hack string immediately after /d that is a "1" (i.e. the number ONE) NOT a "small L". They look the same when typed in a DOS window, but are obviously different. See below:
If you are copying and pasting these strings into your CMD window, it should work fine. I watched the video on my ipad and then tried to re-write the first string into the CMD window on my laptop since I couldn't copy and paste on a different machine. I initially got a syntax error saying /d had an invalid value. But, once I changed the small L to the number ONE, the operation executed succcessfully.
