I have an XP computer that had a virus, but is now clean. The virus broke Microsoft security essentials so it was uninstalled. Other antivirus programs can be installed, but MSE shows an error 0x80070645 during install and aborts. I tried the MS Fixits for both version 1 and 2 of MSE without any help.

Make sure all entries are deleted from registry:

IMPORTANT:
Back up the registry before making any changes to registry.

HKEY_CLASSES_ROOT > Installer > UpgradeCodes > 1F69ACF0D1CF2B7418F292F0E05EC20B
[Right click and delete the key]
 
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Installer > UpgradeCodes > 1F69ACF0D1CF2B7418F292F0E05EC20B
[Right click and delete the key].
 
- Restart computer.
- Upon restart try installation again.

Also take a look at this article from Microsoft, you mentioned that FixIT did not resolve the issue, try manual steps as per the article:

Those upgradecodes entries were not in the registry.

I searched the registry for the following terms and all have come back without any items found:

1F69ACF0
Microsoft Antimalware
Microsoft Security

I have run sfc -scannow and there were no issues.

#1. Open command can you list directory "c:\program files\Microsoft Security Client" and send the output list.

#2. Uninstall left some residue of files / folder which is conflicting with new install. Try removed based on this article:

There is no Microsoft Security Client folder in program files. I see that one gets created when I attempt to install the program, but the only file that populates in the directory is a EULA rich text document, and then the folder is deleted as the installer reports the failure and cleans up the installation.

I tried the items in the second link, some of which I had tried before. I had high hopes for the batch file cleaning up items, but it still does not work.

#1. This article is not related to the error you getting, but it explain how to monitor process while installation and trace down on issue which is blocking a successful installation, using Sysinternals Process Monitor (http://technet.microsoft.com/en-us/sysinternals/bb896645).

#2. Is there another anti-virus program installed, if so try running a virus scan again to check if machine is affected by virus. If there is no malware found, uninstall anti-virus program and try installing MSE.

I found a copy of MSE v1 and it installed properly and then the upgrade to the latest MSE worked fine. I still don't know what was keeping the original v2 install from working.

This is what worked when all other attempts did not.
