I want to use the tf library of 4.5.6 firmware, which ADAPTS to my old code. Firmware tf libraries above 4.5.6 were deleted.
After I installed the IDE version 4.4.4, I couldn’t connect to openmv h7 plus with the old firmware 4.5.6. Before that I was using 4.1.8 IDE and everything worked fine.
After updating the IDE version 4.4.4, I uninstalled the IDE version 4.4.4 and re-installed the IDE version 4.1.8. Maybe the registry was not deleted cleanly, resulting in the IDE version 4.1.8: the system could not find the specified file error.
Now I want to go back to 4.1.8, but I don’t know how to uninstall 4.4.4 clean.

Hi, when you launch the old ide pass these command line arguments to it:

-update_resources

You only need to do this once when launching it. It will blow away the settings for the new one.
