Exit Code 105: Unable to open file

This is the error I get when trying to update the firmware on a MC7750. Any idea what might cause this error?

Hello,
It seems the path of the file is incorrect or file is not present at the path given. for more information can you please provide more details about your use case like which OS you are using windows or Linux and which tool you are using to download Firmware.

Thanks & Regards,
Rex
