I am suddenly unable to launch the Admin Console using Java 1.8.0_251

I searched, and all the threads are old. I cleared the Java cache and even tried reinstalling it, but no dice.

I recently upgraded from v4.7.3 to v5.0.16C, and was able to log in after the upgrade. Fixing my scenes...that will be another post, LOL.

Thanks for any assistance.

Add ISY to the java permissions table under the "security" tab.

I'm not sure if you're experiencing the same problem I had recently, the symptom was you would click the launcher and then briefly see the Java logo it would vanish and nothing else would happen.

The solution to that was:

1) uninstall java completely

2) navigate to C:\Users\<username>\AppData\Local\Sun\ and delete the entire folder named Java

3) reinstall java

Thanks for the replies. Unfortunately, neither solution worked for me. The symptom is that when I launch "Start.jnlp" from the desktop, the "UD" icon appears, and then disappears, but in task manager, the Java Web Launcher (32 bit) is running.

Here are the steps I took:

I uninstalled Java using the Java exe, and the remove option.

Then I restarted the computer

Then I reinstalled Java, restarted again, and then tried launching it again (fail)

Next, I added the ISY to the Java Control Panel -> Security sub-tab -> Exception Site List -> add my ISY's IP Address as a URL (i.e. http://192.168.1.100)

 

 

 

Update: Fixed!

I used some different keywords to search, and found another thread that prompted me to use some different keywords, and I found another thread, which led to a post from @Michel Kohanim with the solution that fixed the issue. Since I only use Windows defender, and the Java was running, I knew it wasn't the antivirus issue, but I do run multiple monitors, so found the files noted in the Wiki and deleted them, and I am back in business. I guess the lesson is to describe the symptoms in the Google search, and it probably would have brought me directly to the solution. The question is why did this happen all of a sudden, but I guess that is Windows for you. ?  Anyway, for reference:

Admin Console Minimized/Invisible and Cannot be Restored

This is usually related Admin Console state files not being updated properly and especially in case of multi monitors. All you need to do is to find the following files in Java temp directory (on Windows: c:\Users\[Username]\AppData\Local\Temp) and delete them. Or, you can simply search the computer for udi_*.* file patterns:

• udi_tree.state
• udi_frame.state
• udi_pgm.state
• udi_finder.state
• udi_launcher.state
