Hello
This error typically indicates that a required dependent assembly is missing.
Here are a few steps you can try to resolve this issue:
Check for Missing Dependencies: Ensure that all necessary runtime libraries and dependencies are installed. Sometimes, installing or updating the Microsoft Visual C++ Redistributable packages can help.
Reinstall Libero SoC: Try reinstalling the Libero SoC software. This can sometimes fix issues related to missing or corrupted files.
Run as Administrator: Make sure you are running the application with administrative privileges. Right-click on designer.exe and select "Run as administrator".
Check System Compatibility: Ensure that your operating system is compatible with Libero SoC v11.9. Sometimes, running the software in compatibility mode for an older version of Windows can help.
If these steps don't resolve the issue, you might want to reach out to Microchip's support for more detailed assistance.
