Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
A combination of netfx (.NET fix) and o15ctrremove (Office removal/cleanup tool) solved the issue for me. This worked on all three laptops that I've tried it on.
This worked perfectly for me. Installing as a local administrator and removing the PC from a domain did not work, but the .NET Fix tool and running the Office removal tool worked. Thank you!
