Issue:
Upgrading from 6.5.0.1221/1222/1223 to 6.5.1.406 causes Maxadministrator to hang and some services may not start.
Cause:
The SP firmware in 1221 and above is newer that 6.5.1.406. So when 6.5.1.406 is loaded, the firmware is no longer correct.
Fix:
After loading 6.5.1.406, stop services by using the AltiGen Services Utility and immediately load the latest released QF for 6.5.1.406. The latest updates are available at the dealer website.
Start up the services. A reboot is not necessary.
This will update the firmware back to the correct version.
