Ignition Designer Launcher Error

Every time I try to launch my Ignition Designer, I get a “Launch Error Occurred” message. “Java process launch failed with error code 1: Error: could not open…”

I’ve updated and configured my Java settings, so I’m not really sure what else to do…?

Any help is appreciated. Thanks!

Same error for me after updating to 8.1.2

I am getting this error as well. Design Launcher log shows:

I am getting the same error on version 8.1.2. No solution yet…

Update, found the solution to my issue on another thread:


I had the same issue but it was not in the same place.
I had to go to C:\Users\username.ignition. User name represents the name of the user on the computer. I deleted the Cache file and it worked.

Please find the screenshot given above


How much memory is the designer set to use? (In the gateway’s settings.)

How much memory does your workstation have?

8GB Memory!

You didn’t answer both questions. Also, for the workstation, it matters how much is free.

Report this setting from the gateway:

And these settings from the Vision project you are launching:

4 GB is used in designer memory and client memory !

Ok, now how much free memory do you have in the workstation?

Hi, I trying to lunched design this error do appear

Try going to that path and deleting the 11.0.16 folder. It will force a fresh download of the runtine.
