The software reports "Protection Lock Error" and will exit

It can be caused by a number of reasons as follows, but you might want to read user's manual in more details to understand our licensing mechanism.

  • Your license might have been invalidated because of significant computer change. This is not allowed by design.
  • You chose to let the license remain "online" while you're not able to keep the NVR server always keep connected to the Internet. Without Internet, online license will only remain valid for 3 days, and after that you receive this error. If this were the case, you should commit the license to "offline" to avoid this problem.
  • You try to backup a license from a computer, and restore to a different one. This is not allowed by design.
