@BetterRed; Sorry for the late reply. After further investigation, it is not a Calibre problem.
The reason is my browser downloads go into a location which is a special type of reparse point known as "Dos Devices".
The installer cannot be run from there, and the 'correct' way is to either move the installer away, or run the 'real' path on the original location, avoiding any sort of symlink etc. redirection.
