A Microsoft application for managing email, calendars, contacts, and tasks across devices and platforms.
You are creating a file in Notepad.
Just open Notepad, copy and paste:
<Configuration>
<Updates Enabled="TRUE" TargetVersion="16.0.12624.20466" />
</Configuration>
Then save as "Config.xml" in the same folder you put the Setup.exe file in. (I just made a file named "Office" and put both in there.)
