Which of your drives is your boot drive?
The Launcher is installed on the boot drive\Program Files\WindowsApps\ folder of which access is protected by Windows.
I can’t access it to move it because I don’t know how to change the security options to access it.
And, I don’t want to.
And, when FS2020 installs, the Launcher is installed and then the install screen is displayed. You, then, can change to install location if the
“Installed Packages” if you want to.
That is what I meant by “mandatory”.
Per TenPatrol above, the launcher can be relocated.
But for what purpose. 2GB of data?
