So trying to Uninstall V18 to Install V20 and run Uninstaller from Server 2016 Add Remove Programs and just keeps looping to do you want to cancel. If you click Yes then ends if you click no you get to click uninstall again and it again asks you if you wish to cancel!
 
18 update 2 is old enough it can't activate, or upgrade directly to v20. I'm not sure offhand what v18 version is required, specifically, but 3CX recommends using the latest, update 9a, and that's all I would use. Can you upgrade to that?

I don't have a direct answer to your question. Have you tried restarting that server, then uninstall again?

I might take this opportunity to set up Hyper-V, install the Linux version of 3CX v18 into a VM, and restore your backup to that. Also that way you won't need an Enterprise license which will be required for Windows going forward. Then upgrade to v20.

Unfortunately it's showing as no updates available to upgrade! Have restarted server and still wont uninstall. Unfortunately can't find any V18 downloads to get a 9a but that would require an uninstall / reinstall the same as 20 anyhow wouldn't it. Unfortunately our backup solution won't allow any more VM's so will need to keep on the Windows VM currently on.
 
Your license is probably inactive or at least can't communicate properly with 3CX's servers. There were a few required certificate updates last summer/fall.

Yes I think you'd still need to uninstall to move to 18u9. We've actually never installed the Windows version and don't have any in our fleet at the moment. Is there nothing in Windows' Application event log? I would assume there's a log file somewhere.

Downloads links are in your customer portal. For v18 change

Interestingly 18.0.2.307 is the software version through Windows Programmes is V18.0 (Update 9) in the 3CX Control panel so am on latest Version of 18 by the looks of it. Running on a Windows 2016 server so debian links won't help unfortunately.
 
Are you talking about the Desktop App? The Problem ist this version was compromised and your antivirus just deleted some stuff. Now its not possible to uninstall automatically. You need to clean it manuel.
