Unable to start Talend Studio

[TalendSolutionExpert]

Talend Studio does not start and displays an error message:

An error has occurred. see the log file /studio/configuration/xxxxxxxx.log

The log files read:

!MESSAGE Application error !STACK 1 java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).     at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:81)     at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400)     at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:255)     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)     at java.lang.reflect.Method.invoke(Method.java:498)     at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:659)     at org.eclipse.equinox.launcher.Main.basicRun(Main.java:595)     at org.eclipse.equinox.launcher.Main.run(Main.java:1501)

Cause

Cached values.

Resolution

To clear cached values and recreate certain configurations:

1. Close Studio and go to the Studio installation directory.
2. Open the configurations folder and delete the folders that begin with org. -- except org.talend.configurator.
3. Restart Studio.

If the issue persists, create a backup of your workspace, then switch to a new empty workspace and try to pull your projects again.

Based on my experience if the methods above still do not resolve the issue then the user may need to reinstall Talend Studio.
