On July 15, 2020 Microsoft released Office Version Version 2006 (Build 13001.20266 Click-to-Run)
Of course, quality control isn’t their strong suit these days, and for many people Outlook starting crashing with this error in their event logs:
Faulting application name: OUTLOOK.EXE, version: 16.0.13001.20266, time stamp: 0x5ef262ee Faulting module name: mso98win32client.dll, version: 0.0.0.0, time stamp: 0x5ef2aa2d
One fix is to put this in a batch file and run it:
rem Fix for the following problem:
rem Faulting application name: OUTLOOK.EXE, version: 16.0.13001.20266, time stamp: 0x5ef262ee
rem Faulting module name: mso98win32client.dll, version: 0.0.0.0, time stamp: 0x5ef2aa2d
%SystemDrive%
cd %programfiles%\Common Files\Microsoft Shared\ClickToRun\
officec2rclient.exe /update user updatetoversion=6.0.13001.20384
This fix does not require a reboot, but does require that all office applications be closed.
Note: Previous versions of this fix used the June 24th build of 12827.20470, but the above patch uses a newer, fixed build that incorporates other security fixes.
