BLE FOTA update cannot find "Could not find file 'CP210xRuntime-x64'"

Hello,

I am currently working on FOTA and I was able to do the upgrade following the Firmware Over the Air guide. Even though fota seems to work, when I try to update the firmware after loading the Bootloader using updater.py I see this message "Could not find file ‘CP210xRuntime-x64’. There is CP210xRuntime-x64.dll file present in the folder of updater.py.

Where is it looking for this file? How can I fix this error?

Thank you.

One thing that might be an issue is the version of Python. This was tested with ver. 2.7. Can you retry with ver. 2.7?

See screen example of bootloader/scripts folder with -x64.dll file.
