Registry Key
32-bitHKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core
64-bitHKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Paessler\PRTG Network Monitor\Server\Core

There are three ways to set access rules for the related registry keys:

  • Manually set permissions in the Registry Editor
  • Use the script we provide
  • Change the group policies permissions
