This error could indicate that you are trying to upload the Firmware from within the compressed .zip file.  
Extract the file to it’s own folder and upload from there.

Kind regards, Gero

Well thanks for that, it was as you said. The zipped folder appeared to be unpacked and the zip symbol had gone from the folder creating the impression it was unzipped when in fact it was not. Trying it again got things going. Thanks again.
