The problem I was having was unpacking the zip file after download, before the USB drive even came into the equation. It’s something to do with the compression algorithm. I gave up on 3.3 and installed 3.4 no problem. Although I got an error with a USB3 drive. A USB2 drive worked fine.
I honestly think that it is a combo of the compression algorithm and the POSIX 591 permission that the compression utility throws onto the file. The mac formatting of the usb drive and doing all operations on that volume seems to negate the issue.
