I just upgraded a production server from 8.0.8 to 8.0.16. After the upgrade and after the Gateway was running, I tried opening the Designer and got and error dialog. ![Error Launching Application](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/9/e9a0eb3dfd1b7c17f737cddfc57ceab1156f4166.png) Thinking it may be due to the old Designer Launcher, I uninstalled the launcher and downloaded it again from the GW webpage. After installing it and when the launcher started, I got this error again. Anytime I try to open the designer I get the error. I can open a designer from a remote machine for this Gateway. Any input on correct this would be very appreciated since this is a production server. Thanks! ---

If you delete `~/.ignition/cache` on the machine you’re trying to launch from does it work? ---

Nope. The system does rebuild the cache, but I still get the error. I am getting launch\_error\_###.log files generated though. They don’t mean much to me, but someone who understands the content might make some sense out of them. This client has 3 servers. One is a development server. One is a validation server. The last is a production server. I’ve upgraded the dev and val servers with out having this issue.

Can you upload that log file that gets generated as well as `~/.ignition/clientlauncher-data/designerlauncher.log`. Might also be worth trying just deleting all of `~/.ignition` and launching. ---

Edited my previous post when you replied. I added the files there. Thanks. ---

@Kevin.Herron I deleted (moved actually) the entire .ignition folder and tried launching the designer again. It WORKED this time! Thanks for the help!
