Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have tried to open a word / excel document.
It says it is updating, please wait a moment.
After a few minutes I get a message saying:
WINWORD.EXE - Application Error - This application was unable to start correctly (0xc0000142). Click OK to close the application.
Another user tracked this down to Office waking from the computer put into sleep or hibernation earlier. I always leave an Office file open when I put computer to sleep now. Not sure but seems to work. Otherwise, shut the computer down when the Office update box appears BEFORE the error box appears. And then reboot, of course.
