PRO upgrade

Attempt to register upgrade license key fails with message "Invalid response from server".


  • Any help with this problem will be appreciated.

  • Did you buy a upgrade license instead of the full pro version? You can send us the license number if unsure and we can send you a link to buy the required OEM to convert it in a pro if that is the case. Please do not publish license here!
  • The license is described as "Repetier-Server Upgrade (OEM to Pro)"; so it would seem that your thoughts are probably correct. When I go into the Register screen it states that I'm on a Pro version trial; and can "upgrade at any time" !! so is this a different issue to the one you suggest? 
  • Yes the triel just means you have no license but can use all pro features. You need a OEM license installed first than you can convert the cheaper OEM in a full pro. I send you the link in a PM.
