One of our client has Ignition 7.7.7 (x64) and Java version 1.8.0_251 (previously it was 1.8.0_181).
After lock-down we found that the Ignition server is running but we are not able to launch designer and client. Ignition server and client is on same machine. We are getting error while launching designer or client “Unable to launch application” and stack is as per below.
We have reinstall java and Ignition still not able to resolve this issue. We are using Windows 10 OS.
