Definition Update for Windows Defender - KB2267602 (Definition 1.213.5087.0) - Error 0x80070643

I can activate windows defender...it is grayed out.

Should I assume this is because of the Norton Security?

Although did not have this issue for past months when running Norton on Windows 10...

I disabled Norton Security and still could not turn Windows Defender on, and same message when trying to update Win 10...

I have not been able to download  windows defender  KB2267602 under error                   OX80070643....for a least 5/days...pls he/BG5050/******@outlook.com......thks....

When I run the command, I get the following

FYI, I'm running Norton Security.

DIDN'T WORK FOR ME!!!

I uninstalled NIS several times and it fixed the problem, UNTIL I RE-INSTALLED NIS and there it was AGAIN....THE SAME "F*(**&*&**&&" PROBLEM!!! That GD error CONTINUES TO SHOW UP!!!  With all the "mental giants" that work for MS, one would THINK someone techie would SOLVE the problem. I know the answer WHEN will MS.....FIX IT???
