I'm also having this issue. Would you be able to assist me as well?
I have an R7, and had no problem downloading and re-installing the CC EXCEPT that the OC page was not included. I had to download this separately. I have no other info.
Problem solved! I was able to find and install the Windows 7 version without an issue.
Cannot install command center on m17xr2 with win 10 upgrade. installed r272621 but video crashes on boot.
