Hi,
While trying to activate the GUI, I receive the following error:

Error: Could not find or load main class com.exalttech.trex.application.TrexApp

Info:

Java Version

[root@localhost trex_related]# java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

$JAVA_HOME

[root@localhost trex_related]# echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre/bin/java

Trex Version:
2.61
GUI Version:
v4.5.6 (9778e1d)
OS Version:

[root@localhost trex_related]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)

* Double clicking the JAR file opens it in File Manager

Any thoughts?

Thanks!

Hi Egor,
Thanks for replying.

I eventually solved this issue by downloading the .exe file to a MS Windows PC, and simply connecting the GUI (via network) to my Linux PC running the Trex server.
