I see. For now I don't know what else you can do to solve the issue. It happens to me as well sometimes. I turned off said program, it helped. The other time I did that, it didn't. I will need to further investigate. If I have a solution and I don't forget our little chat, I will let you know ;)
Hi TM,
I know that kind of problem, having spent a significant part of my life in maintenance. When the root cause just will not reveal itself any change you make to fix the problem is really random and may or may not actually impact the problem at all. In the worst case this all you can do, and is fine as an approach until further evidence turns up. I would appreciate advice from you if you turn up further evidence related to the observed problem. Should you want further details of my system feel free to ask.
As well, I will:
1) Try a fresh download and install of the game. My system took Win 10 patches from Mr Microsoft on that day, which might have needed a proper reboot to finally install, not to mention that Mr Microsoft has bugs of his own sometimes. That reboot has now been done and the problem may have cured itself. If so I will let you know here.
2) If the installation fails again I will wait until the next release and try again.
Thanks again for your assistance.
Regards,
