RealCAD Reissue Key

If your RealCAD license needs to be transferred to another machine, or if your hard drive fails or you upgrade your PC you will need to get a new license key (fee applies).

Important Information About Moving Your License

You may move your single user license from one machine to another. CAD International require that you MUST use the 'unlicense' process outlined below before issuing any new replacement software key to you.


  1. Select Help > About from the pulldown menu
  2. Select the Unlicense button and follow the instructions, (save the licenseinfo.dat file that it creates to your desktop)
  3. Regardless of whether the software says it has emailed us or not, manually email the licenseinfo.dat file as an attachment to support@cad.com.au with your request for a new license Key.

We will process your request and return an email to you with further instructions on licensing your new machine.
