In June 2009 we’ll publish Refresh 2 of the AX 2009 Demo VMs. If you are using the Refresh 1 VM you will need to update the AX License in there. See my previous note on the Expiry of the VMs
You will be able to find a updated license for AX on the VM page on partner source here next week :https://mbs.microsoft.com/partnersource/deployment/documentation/howtoarticles/presalesdemokitmdax2009.htm
When you get that file the following video will help you out with how you update AX on the VM.
