Solved Unable to Update to v15 SP6.

My 3CX license expired while I was on v15.5.13103.5. This version prevents communication with the activation servers. I'm unable to update to SP6 because the license expired on January 3, 2019. I'm unable to reinstall the latest version because I am running the software on a Windows 7 VM & a newer OS is required.

The license was renewed in December but because of the following error, I am unable to refresh my license key information:
"3CX failed to establish a TCP connection to activation.3cx.com.
Ensure that the local or border firewalls are configured to allow outbound traffic to activation.3cx.com"
This is a know issue fixed by SP6:

& more!

I thought I could fix this issue by reinstalling but I'm unable to update the software manually by downloading the latest version as the latest version requires Windows 10, Server 2012R2 or Server 2016.

Aside from reloading the OS & reinstalling, are there any other options?

Yes 3CX made a tool to upgrade 3cx V15/V15.5 to V15.5 SP6. https://www.3cx.com/blog/news/pbx-upgrade-update-6/

Thank you! This update tool worked and I am now running version 15.5.15502.6. The server was able to verify the license status and I was able to install the latest updates.

Glad to see the issue has been resolved and you were able to activate your licence. If you are running the PBX on an unsupported OS i would recommend upgrading the OS to avoid any issues and to be fully supported.
