Weka

Close Weka before running a managed Windows update. The Windows EXE update can return Exit Code 1 when Weka is still open, so Intune, ConfigMgr, RMM, or software-center packages should use a Weka-specific conflicting-process step or schedule the update when users are not running the application.

For packaging and later troubleshooting, keep the installer source tied to the official Weka project/download pages and the SourceForge file area linked by the project. After install or update, validate the expected Weka build starts successfully rather than treating a generic non-zero installer result as interchangeable with other Java desktop apps.
