License Key on new pc desktop

On October 4th, I purchased a license for Aomei Backupper Professional Lifetime from a vendor on Ebay. The program was installed and worked well until about 3 weeks ago, when I bought a new desktop PC on which I transferred everything. However, the Aomei Backupper software no longer works because it does not accept the license key that was provided to me in October. So please give me instructions on how to proceed. Thank you.


  • Follow the procedure with the offline-key:

    Step 1:Turn off your internet connection while you're registering the software. You can see the Machine Code just as the screenshot below and copy it.

    Step 2:Turn on your internet connection,and click the link

    step 3:Enter your license code and machine code into the right place as the picture below.

    Step4: you will get an offine key , and then enter it into the box of the registration interface(offine key).
