Upon installation of PRTG I have received this error. The installation competed following downloading the file and running the setup.exe. I followed the wizard and when I got to the end it was successful and opened a window with this error.

Has anyone got the solution for this?

Hi, please check which port PRTG is using for it's web server. You can use the program PRTG Server Administrator for this purpose. It might be that the standard ports are already occupied, then PRTG switches automatically to port 8080.
Best regards
