I had a script someone shared that updated advanced gam - and lol @ me I ran it this morning thinking it might still work.. it does.. if you want advanced gam 7.05 instead of Gam7 :)
Don't fret - I downloaded the MSI to correct my blunder - but was wondering if there was a new script out there that would shave a few seconds off my day from going to Github to check for new releases ?
If not .. I'll survive .. this is a first world type "problem" after all. :)

This is a newer version I believe - less "wordy" than the one I just posted:

I just added a pull request for that version of the script, to automatically determine the gam installation location and Windows architecture version, to make the script a little easier to use. I don't have an ARM system to validate the ARM piece, but otherwise my testing of the script seems to work as expected:
# Just like the script for GAMADV-XTD3, this is not my script originally.
# It was created by Chris River (on request by Gabriel Clifton) and amended by Paul Ogier.
# That process can be seen here.
# https://groups.google.com/g/google-apps-manager/c/k2JEsdT6jcs/m/DdrLY_GcBQAJ
# I updated the script to make it possible to run the script regardless of where the user is, and also to run it automatically.
# This script must be run as an administrator
# Check the version of GAM7 and update if new version exists
## There's now an ARM version for Windows, so code needed one more variable.
# Set this to $false if you do not want to see the change log output
$ShowChangeLog = $true
# If GAM's installation location cannot be automatically located, then this variable MUST be adjusted to match your system.
# Where is GAM7 installed?
$dir = ""
# Try to automatically find the install location for GAM
