Dear Dave,

what is the Java version on your machine? You can use “java -version” to find out.  
The error is typical for the case that the software has been compiled with a later version of Java than the one you are trying to execute it with.  
What do the release notes say about the minimal Java version required?

Best regards,  
Jozef

Thanks, Jozef! It turns out that is in fact the issue. I’m re-writing our batch/CLI scripts to use the java.exe that comes with Pinnacle 21 Community, and that should solve it.

Trying to invoke the CLI validator in Pinnacle 21 Community v2.1.2, and I’m getting the same sort of errors I was getting previously:

Is there any known work-around? Is the CLI validator no longer a supported tool?
