The trial version of PRTG has been working but I am approaching the end of the trial and, since I am using this at home with fewer than 100 sensors, I would like to continue to use the freeware version. However, the PRTG Core Server Service will not start. When I try to start the Core Server in Windows Services, I get the error message "Windows could not start the PRTG Core Server Service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion." I have tried rebooting, uninstalling/reinstalling, and several other suggestions from your Knowledge Base and Google searches. Please help.
