Issues with Trial Licence when linked to a MAC address

Machine details:

The issue is that GraphPad links the use of a trial machine to a MAC address. When the Fresh Start machine is cloned, it will typically retain the same MAC address. Normally this wouldn't be an issue, but here the application reports that the licence has already been used, as it was on a previously cloned machine. The machine might be on a different server or even in a datacentre on a different continent, yet it will still report this error. 

The workaround, therefore, is to change the MAC address. This is straightforward in Linux and well documented, but rather less so when using Windows.

Changing the MAC address within Windows through the usually recommended methods won't work, as the machine's qemu.conf file will override the MAC change inside the virtual machine. Thus, you can alter the MAC address in Windows 10, but by itself this still won't have any effect.

This is because the qemu.conf file contains a configured MAC address. Changing this address will provide a different MAC, thereby allowing a different licence key to be used. 

However, to make this work, you'll need to set 'Network Isolation' to 'Disabled' on each machine; the MAC address specified in the qemu.conf will then be applied.
