SOLVED: Error 0x80072EFE Cannot activate Windows or Office

If you can not activate your Microsoft Office, try disabling your AntiVirus.

In my case I received 0x80072EFE when trying to activate Office 2013 using an MAK (Multiple Activation Key) and I had to disable Kaspersky 8 End Point Security with patches A, B, C, D and PF80).

We have a call into Kaspersky and I will update this with there response in the coming days.

FYI, I got the idea to dump Kaspersky from http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_install/0x80072efe-cannot-activate-windows-or-office/13b293c3-2aca-42b4-99a6-f3cf2723286d
