java.awt.AWTError: Assistive Technology not found

Hi,

We recently upgraded a customer to the latest 8.1.37 version. Most vision clients did handle the upgrade well, except for one client that keeps on receiving the following exception and isn't able to start the vision client. Any suggestions on what the cause could be?

Thank you,

Open a terminal, navigate to the embedded Java runtime on that client (in something like ~/.ignition/cache/resources/runtimes), then change into the actual version you find, then the bin folder, and trying running jabswitch.exe /disable.

If jabswtich doesn't exist in there, see if there's another version of Java installed on that computer that does have it.
