Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
i had open the regedit at the time of trying the install.the reg does not change at anytime during the process.or even after you close it down after failing to get past the start.It opens then you do the product validation ,press continue,check the box for agreement ,the it just waits fora moment then hangs with the all tooo familiar note.
