Hi all, I also had this issue after upgrading from Windows 8.1 to Windows 10, I tried all the suggestions below but none helped, at one stage I was going to restore to my old win8.1.

Recently I installed Zwift, which is a cycling program that requires an Ant+ dongle, anyway the error returned, frustrated to say the least, I finally spat it and decided to reinstall Windows 10, now no issues, when I installed Zwift again I got a message that it needed Microsoft.Net/Framework ??? which it installed and all is OK, all the programs I had the issue with now run fine.

I hope this helps.

Cheers Rob
