"mbukernel" errors on launching Microsoft Office 2011 apps

Thorny problem here recently with Microsoft Word. Attempts to launch the app failed with a crash. The operating tech was at the point of being ready to reinstall the suite, which is in itself a thorny process, thanks to MS removing the Remove Office tool. But I digress.

Adding to the problem is the fact that removing and reinstalling the suite would have solved the problem, but provided no clue to the cause.

Here’s the relevant block of text from the crash log:

Library not loaded: @rpath/mbukernel.framework/Versions/14/mbukernel

Referenced from: /Applications/Microsoft Word.app/Contents/MacOS/Microsoft Word

Reason: image not found

If you see a similar error, your first step should be to put all your Office apps back in the Microsoft Office 2011 folder, then try again. Apparently, Office programs don’t like being pulled out of their snug little abode, and there will be much wailing and gnashing of teeth of they are not returned.
