So far, the only other person we are aware of with this issue did have corrupt system files. As @Alain Verleyen points out, many of us have not had this problem running the same O/S (and the same third-party software).

Have you run SFC and did it come up clean? If so, we can move on to look for other causes.
There was no confirmation that there were corrupt files in that thread. In the last response, someone asked him to check the services from task manager. I've run SFC and it didn't help.

Yes, there was - https://www.mql5.com/en/forum/170584#comment_4107544 

But if yours came up clean, I guess the problem is elsewhere.
