This morning, I updated to Java 7 Update 25 (build 1.7.0_25-b16). Also this morning, we upgraded to Ignition 7.6.1. Suddenly, I found that I could not open a Designer and Client at the same time. I can open one or the other, but must close the first before I can open the second.
When I attempt to open a second Ignition Client/Designer, I get the following error:
“Error launching application:
JARSigningException: Could not verify signing in resource:
172.28.33.236:80/main/system/jar … client.jar”
For completeness sake, I tried opening two Designers, or two Clients. Both attempts failed with the same error.
I am running Windows 7 Enterprise w/ Service Pack 1.
My coworker appears to be having the same issue.
We use Firefox 17.0.6 to launch the applications initially. Not sure if that affects anything.
