We're installing the full-licensed version of PRTG on a secured server.
After the installation, the Core Server Service will not start. It seems to be hung, just shows "starting" in the services console.
We did have the free version installed on this machine previously. Per the emailed instructions we received with our license key, the old version was not uninstalled prior to the new install.
The server has no outbound internet access. We did try installing the root certs as recommended in another post here.
