Older versions of Replay Converter may not be able to access our registration server to activate the program. Updating to a newer version is the best course of action. But for those that do not wish to update, here's the workaround:

  1. Download register.zip from here: http://downloads.applian.com.s3.amazonaws.com/Register.zip
  2. Unzip to find register.dll
  3. In Windows Explorer navigate to the folder where Replay Converter 4 resides. Likely C:/Program Files/Replay Converter 4
  4. Copy register.dll into that directory replacing the file of the same name currently there.
  5. Close Replay Converter and re-open. You should now be able to successfully activate.
