Please read my original message about NOT logging in.
Hi,
Thanks for your help. I found a link for v6, so that solved it. 
Thanks for confirming.
Found Windows on ARM versions here:
But not to download and install.
Not sure why not logging in is a requirement. AFAIK you can’t. Is this an automation thing? E.g pull down a version to an MDM to deploy from a script?
I finally found an “official” source of the newest GP version - you open the https://pan-gp-client.s3.amazonaws.com/ website (in Edge/Chrome it opens as a readable XML), then you look for the version you want (the newest one is at the end of the XML). For example if you need the newest Win64 version you copy the last “key” value (“6.2.3-270/GlobalProtect64.msi”) and append it after slash to the end of the link like that: https://pan-gp-client.s3.amazonaws.com/6.2.3-270/GlobalProtect64.msi
You’ve just generated a link to the newest GP version
Why go trough so such a hassle to find a download link without logging if it is for an automation purpose just download the client logging in your own portal and host it without authentication yourself and thats it
He probably doesn’t have an active contract?
