Cant install Microsoft Security Essentials Error Code 0x80070643

Cant install Microsoft Security Essentials Error Code 0x80070643


Problem:  You cant install Microsoft Security Essentials and get an error coder 0x80070643.

First, be sure to go through these steps.

But when I found that this didnt help, I kept digging and realized I have was having other problems including not being able to open the Management Console or searching from the start menu.  Error 1606 also appeared in the event log.

Thats when I came across KB886549, which addresses some registry settings pointing to user profile locations. Just run the "Fix it" button and youre set and should be able to install Microsoft Security Essentials.
