Invalid hardware key?
This only happens on a physical PC if your hardware has changed significantly (e.g. change of mainboard or complete PC ...) or on a virtual machine if the MAC address of the primary Windows Network interface has changed.
Usually an activated XP/VS license is bound to the hardware of each machine.
However, based on manual requests we do allow reasonable reactivation requests. e.g. if your hardware breaks, or you change your server, etc.
You can release your license three times by yourself, without having to wait for our support team to reply:
Reactivate/Transfer a license
Activate XP/VS Server License
In case it is a virtual machine, please assign a static mac address before you activate your license again.
