For context KB3114409 was that update for Microsoft Outlook which caused it to get stuck into safe mode. Link

When I try to uninstall this update from machines using WUSA.exe and this command:

wusa /uninstall /kb:3114409 /quiet /norestart

I am told that the update could not be found on the computer. However, if I check it through the Control Panel I can see it and uninstall it that way.

I believe this is something to do with the fact we have a 32-bit installation of Microsoft Office on a 64-bit version of Windows which is why using WUSA fails.

Can anyone shed some light on this?

WUSA is only used for Windows updates and patches, not Office. You can use MSIEXEC in the following fashion:

msiexec /i {90140000-0011-0000-0000-0000000FF1CE} MSIPATCHREMOVE={14CDCBF7-3CCC-42E2-A5BB-2D4926E16FAA} /qn

You should likely force close Outlook prior to uninstallation. But I haven't tried without closing.
