2, the system is not compatible, you can choose to re-download the compatible version.
3. When installing Mitsubishi PLC programming software, GX Developer has selected “Monitor-specific“. So it can only be used for monitoring, not for new projects.
Solution: After uninstalling the Mitsubishi PLC programming software GX Developer, reinstall the software. Be careful not to select “Monitor-specific” during the installation process. After installing the open software, if the gray word such as creating a new project becomes a bold font, the software functions can be used.
