The downloaded file is not a valid installer.

I am currently running PTRG v22.1.75.1594+. The last 2 times AutoUpdate has checked, I have gotten the message "The downloaded file is not a valid installer." I get the same message if I click the 'Check For Latest Update and Download' button.

Hello,
If the auto update download doesn't work, this can happen if your firewall or UTM is blocking the download, you can download it manually from our download server:
https://downloads.paessler.com/prtg/prtg.zip

If you want to ensure that your network security solution isn't blocking the download please ensure that the domains mentioned in our KB article (KB: Which Servers does PRTG connect to for Software Update) are allowed and whitelist if necessary.

Kind regards,
Johannes Beyerlein, Technical Support Team

I have reviewed the kb and my firewall is allowing all the correct domains.

Additionally, I downloaded the update manually and when I installed it the PRTG Core Service would not start. I had to uninstall and reinstall the older version 22.1.75.1594 to get PRTG to run again.

Is there a problem with 22.2.76.1705 and Windows Server 2019?
