Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Folks -
Make sure you can run ose*.exe (ose00000.exe and so on - successive attempts at reinstalling will increment the ose00001.exe, etc.) from your %temp% folder. After CryptoLocker many IT folks put in GPOs that blocked EXEs from launching in the temp folder. Adding those ose00000.exe's as "unrestricted" in a software restriction policy seems to be effective, and Office 2013 setup can continue.
