1. Does CubeEDE v 1.3 need preinstalled JAVA in order to support ECLYPSE? Version of it? 2. How to reinstall CubeIDE v 1.3 after inaccurate CONTROL PANEL erasing (deleting)? 3. Do I need to install STM32H7xxPack during project prliminary settings?

Thank You in advance!

STM32CubeIDE is embedding its own JRE.

Yes FW pack install is required.

You should find some uninstall executable within your IDE install repository.
