Hi @Marcel_Szimonisz 

Can you please check the java requirements as starting v7.4.1 you must generate a JRE as it is no longer provided by default.

Hello @DavidKangni, what does it mean generate JRE? I have defined JRE_HOME env. We have installed JDK and JRE.

@Marcel_Szimonisz 
make sure you have the correct path for JRE

older version of java was creating 2 folders for JDK and JRE

newer version of java 

Not sure if it's related but last time I was installing the latest release I had a java issue and I was able to fix it by checking the JRE path

Hello @DavidKangni,

we installed the newest JDK 23

Also I have seen under programs and features old versions
- java 8 udpate
- java 18

I have removed those and refreshed the JRE_HOME to point to new JDK 23 installation folder and all works/ It seems to me as wrong / old java has been used to start tomcat

Thanks for suggestions,

Marcel

You're welcome. 
When upgrading your Java version, it is recommended to uninstall the previous version. Both versions of Java installed in the same machine can cause conflicts.

Thanks,

David
