Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Look under win10 SETTINGS menu, (not control panel) for OFFICE DESKTOP APPS. i found that when i applied my volume license key to the one of the "Desktop Apps" such as Word, it accepted the key and all seems good. I never solved the error when running the downloaded installer from Microsoft Volume License Center. At this time, i have OFFICE 2016, all of its programs, working perfectly and IT IS NOT VISIBLE as an installed program in control panel. I'm an IT pro, never saw this before....
