No Traditional Windows "Add/Remove Programs" Entry: Oracle JDeveloper releases (starting from 11g and 12c) are often distributed as a "ZIP" distribution. This means they don't always register with the Windows registry. If you extracted a ZIP file, there is no standard uninstaller. Two Installation Types: You may have installed JDeveloper using either:
The ZIP Distribution (Most common) – just a folder. The Studio Installer (EXE/JAR) – which does register an uninstaller.
Backup Your Workspace: Uninstalling JDeveloper will not automatically delete your projects/workspace, but manual cleanup might. Copy your workspace folder (typically C:\Users\<YourName>\JDeveloper\mywork or wherever you saved it) to a safe backup location. Close the IDE: Ensure JDeveloper is completely closed before starting. how to uninstall jdeveloper 12.2.1.4
