I know this is a longshot, but I am trying to support a client who has a super old version of AC, v6.3.3. I have everything working on the server running windows 7 and mostly windows 10 clients but recently the clinic has purchased 2 different HP laptops. While I can get the software installed and it launches and gets to the login screen. Once I type in the password for the user I get a "preloading data for speed. wait a moment" message and then it freezes. Strangely it works fine on at least one other HP windows 11 laptop and all windows 7 thru 10 desktops. I have tried via Wi-Fi and ethernet with no luck. Anyone know why this happens? Yes, I know they are working on re-subscribing and getting support assistance and getting on a newer version. It's a long story on why they are still on this ancient version but here we are..

If anyone can offer any advice I would greatly appreciate it. I have tried compatibility modes and making sure security tools were disabled and UAC. Like I said it does work on at least one other similar laptop with the absolute latest of all windows driver and the same security tools installed and active.

Thanks in advance.
