Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
You can always use a web portal or some other means to email. Outlook is not the only way to send an email :-)
Since I'm not repro'ing this on Win7/Office 2010 it appears to be unique to 2013.
The two that I fixed ARE click-to-run. Office isn't listed under "Installed Updates" and there's a click-to-run service running on the computers. I would assume the third one I know about is the same, but it's in California on a very slow frame-relay connection and I'm in Ohio. Unless we can find a fix I'm planning to have them ship it to me so I can work on it.
And for clarity's sake: All OFFICE programs (for me: 2013 Pro) stopped working after a reboot which was prompted/forced by this week's round of WINDOWS updates.
