Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Do you have Office 2013 installed on the computer?
Integratedoffice.exe is the file responsible for the click-to-run installations of office 2013/365.
If you have installed the off 2013 preview version earlier, I suggest that you run the fixit in this link to remove all the traces. That may solve the log file problem.
