Machine change / upgrade
You can change your machine or upgrade your machine without issue. To do this, first uninstall the software on the machine before performing the upgrade or installing the software on a new machine.
Please note that this only applies to major upgrade, e.g. Windows XP to Vista, regular updates do not require any special treatment.
It is important that you do not attempt to use the software on the old machine after using it on the new, otherwise your key maybe automatically disabled.
Reinstalling the software on the new machine, restoring from backup or transferring the software is allowed.
