Thanks for all of your help, larryllix! For some reason, the crazy thing started working on my laptop today. I can't believe it. I didn't change anything, and there it was---loaded fine. I hope it stays working........... I really appreciate all the concern you and others had for my problem. Have a great Spring.

That's interesting. I have never had it fail until the past few days. How do you reload your saved profile file? How do I save it in the future, so I can fix it?

Update: I installed Java and the IoX Launcher on an old computer I have. It installed fine and immediately found my ISY! So, I know it's a computer problem with my laptop that I have run it on for years. I can't leave it on the old computer, because it's extremely slow and runs my Christmas light show. I need to get it working on my laptop again, but at least I know it's the laptop, not the ISY. Still open for suggestions! Thanks!

Several times I have searched for the *.state files, and they don't appear to be there at all. I just tried again--no items in the search, so nothing to delete. I am running Windows 10 Pro, Version 10.0.19045, Build 19045. My network is indeed set to private (no public network). Removed power from ISY, removed SD card and cleaned its contacts. Replaced the card [the dumb card went between the case and the slot, so I had to take the whole ISY apart and get it out!]. Restored power. Lights behaved as the wiki said they should. No third party Anti-virus or Firewalls are installed on my computer. Still doesn't work. Thanks for your patience and help!

Yes, all instances show as "Java(TM) Web Launcher" in Task Manager. My ISY994i has now stopped controlling anything. None of my programs work (lights turning on and off at sunset and sunrise, etc.), and I can't command with voice through Alexa anymore. It says, "Sorry, the hub that xxxx device is connected to is not responding." I ran the SFC/SCANNOW. The result was "Windows Resource Protection did not find any integrity violations." Is it time to break out the cash to buy a new EISY?

I don't know if this makes any difference to a solution, but I discovered that all the instances where I try to start IoX Launcher are showing as running in the Task Manager. I either have to restart or end each task one by one. So something is still running!

I have done everything on this Wiki several times. I just now took time to do it all again, making sure I paid attention in detail. Still doesn't work!

I deleted Java 8u311, and got 8u441 to load by using the CMD Prompt to install it with the /S ending (silent installation--no user interface). It loaded great. Then I got the latest IoX launcher file from Universal Devices. Still the same thing: UD logo shows for two seconds, then nothing! Over and over and over.....

I am using Java 8u311. For a year or so, my computer won't let me load an upgrade. It shows a script error. I see that many people have had that error. I have tried every remedy I can find to fix it, but nothing works. It has been working fine on this version. I have deleted it and loaded it multiple times. I have ISY994i. I haven't gone to eisy yet. Firmware? How do I tell, if the launcher won't load? What could have changed overnight to make this not work? I have also downloaded the launcher directly from the UD web site. I will search to see how to launch with the Java console enabled. Thanks so much for your help!

Back to where I was when I started this thread. The UD logo comes up for two seconds, then nothing..........

I finally got it to load. On one of the forums entries I found this link, and it worked: https://isy.universal-devices.com/994i/admin.jnlp Now there is another problem--none of my programs are there! All the devices, scenes, etc. are in "Main," and my program FOLDERS are in "Programs," but no actual programs. I tried restoring from a known good backup. After selecting the file to use, I get this error message.

I am on Windows. I just went through the troubleshooting pages again. I have tried everything I can see to do--again. I still get the same thing: The UD logo appears for a few seconds and then goes off, but it never loads the window to select my ISY.

I made some adjustments last night to my ISY, but today the Iox will not launch. The UD logo comes up for a few seconds, then disappears, and nothing else happens. I can click on it over and over, or try to launch it from the programs menu, but I always get the same thing. I also deleted Java and the IoX and reloaded to try again--several times. Always the same result: The UD logo and then nothing. Any help would be greatly appreciated.

Yes, it's a work around, but it works--most of the time. It's a bit finicky, but I'm still tweaking a few commands in my programs. Thanks again.

Thank you so much! After thinking about this all evening, I started doing just what you have written--then I got your answer. I can't believe I came up with the same solution. The only difference is that I don't have a virtual light; I have a plug in module, but it should work the same. Thanks again!
