Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
To further update this, I ran the "cleanup tool" again, tried installing Office 2013 after a clean boot, and tried installing it with Windows Defender disabled....all to no avail. I still get the 2902 error. I did get further in the installation process than I did before, but it still does 2902. Now, there are remnants of the installation, in particular Office 2013 shows up in the program menu, but will not start up any of the programs. Even the clean-up tool I used does not get rid of that. NEEDING HELP BEFORE I TRASH THIS WHOLE THING AND GO TO A MAC! Thanks.
