TortoiseSVN won't stop trying to use Araxis

[bla...@mevion.com]

Uninstalled Araxis and now I can't merge during updates with the following error:

    Error: Can't start process 'C:\Program Files\Araxis\Araxis Merge\AraxisSVNDiff3.exe':  

    Error:  The system cannot find the file specified.  

I've reset every single merge tool and diff viewer setting in the TortoiseSVN settings.

I've removed every single alternate diff script.

I've scrubbed every single reference to "Araxis" in the registry both regedit and regedt32.

I've uninstalled TortoiseSVN, reinstalled multiple times.

Uninstall, reboot, install.

Still:

    Error: Can't start process 'C:\Program Files\Araxis\Araxis Merge\AraxisSVNDiff3.exe':  

    Error:  The system cannot find the file specified.  

wtf?
