Tracker application wont execute

I have tried all the troubleshooting mentioned on the website. I have restarted my system, reinstalled tracker multiple times, but the application won't open even after I click run tracker at the end of the Tracker installer. I'm attaching a screenshot of the tracker_install file and you can clearly see the process of tracker running isn't there

Actually the line "Executing C:\Program Files\Tracker/Tracker.exe &" is where Tracker is launched by the installer. And failed. What happens when you double-click the tracker.jar file in your Tracker home directory?

I double-clicked the tracker jar file, and it opened in notepad. The file was just a bunch of characters. The Tracker application still doesn't open

Do you have any other Java installed besides the bundled java that came with Tracker? Do you have a "Configure Java" or similar control panel on your computer? If not, try downloading and installing the latest Java from https://www.java.com/en/download/.  It should be that when you double-click the jar it attempts to open in Java, not Notepad.

sorry for the late reply, yes I installed it worked for the first time I opened tracker but then after closing the application and trying to open it again it didn't.

If double-clicking the jar file still opens it in Notepad, you need to change the file association so the ".jar" extension opens in Java.

If the jar already attempts to open in Java then that is progress.  In that case you might try using the Java console log to see what errors are occurring. Look at this article:  https://www.java.com/en/download/help/javaconsole.html

J'ai le même problème depuis quelques semaines. Les PCs du labo ne permettent plus de faire démarre Tracker.
Désinstallé, réinstallé rien ne se passe lorsqu'on essaie de le faire démarrer.
