Posted June 24, 2013 Hello everyone. I have been playing wurm for rather long time and today i have come across a problem. When i try play wurm the logo comes up but i am shortly met with... Application blocked for security.Failed to validate certificateThis application will not be executedName: Wurm OnlinePublisher: Code Club ABLocation: http://wurmonline.com/client/wurmclient.jnlp I have tried everything i can think of to get this to work. I have uninstalled java, re-installed it, restarted my computer god knows how many times and gone into the java console and removed Wurm online. Once i removed wurm online the client downloads something then just comes up with this error validation thing again. Please help, I haven't been able to play wurm for 3 days... I feel lost without it. Share this post Link to post Share on other sites

Posted June 25, 2013 (edited) Go to java control panel and check that these marked in red settings are like this: and if the pop up comes up again make sure the box that says to trust that certificate is checked marked, Edited June 25, 2013 by Griffith Share this post Link to post Share on other sites

Posted June 25, 2013 ok try this as last resort click on start button and type appdata then search that file open local low file but before make sure its not hidden and write protected then follow the path ( sun>java>deployment>security) to the file shown trusted.certs and delete it, then try running wurm again hope it helps. if it doesnt then im out of ideas. good luck.

Posted June 27, 2013 Woo Found this thread: http://forum.wurmonline.com/index.php?/topic/43997-java-problem-failed-to-validate-certificate-solved/ Tried this solution: " Go to "C:\Users\YOUR USERNAME HERE\AppData\LocalLow\Sun\Java\Deployment\security" and delete trusted.certs. Then launch the Wurm client and the file should reappear and Wurm launch normally.At least it did it for me! " And it worked. File path is different on XP but you get the idea.
