Question about moving to another computer

I have Avast Internet Security on a computer with Windows 7 home. I recently moved to another computer with W7 business professional, I downloaded the Avast software, installed it and inserted the license. Everything is fine. I shut off the computer. When I restart, Avast loads the ‘free’ software rather than Internet Security program. I remove and reinstall the software, insert the license, everything’s fine - until I shut down and restart - then it loads the ‘free’ version again. I’ve uninstalled and reinstalled no less than 3 times. What am I doing wrong and why doesn’t it remember my license on startup? Or perhaps I downloaded the wrong version?

Any help would be greatly appreciated.

  • Remove the old system from your account
  • Wait e.g. 3 hours (it can take a while before changes take affect)
  • Perform a clean installation of avast on the new system
  • Use your license file
