IMC update failing (Unsupported major.minor version)

Alfred Macher — Mon, 03 Oct 2022 05:53:13 GMT

So, I want to move my IMC installation to a new server. Before that, I'm gonna upgrade to the newest version ("7.3 E0706P11").

My current install is on a WinSrv2012R2 (which is still supported) and has the version "7.3 E0504P04".

Looking at the prerequisites, nowhere is a specific Java version mentioned, but the error does kinda point to that... We've got "OpenJDK 11.0.4-1" installed.

Does someone know how to resolve this issue so I can update?

Thanks!

Woah, that was a long time ago^^

No, I moved the iMC to a different computer and installed the newest version directly.

Sorry that I cannot be of more help; iMC is finnicky AF...
