So poking around some and I tried https:// with the following legacy.bmw.com/_common/shared/owners/bluetooth/bin/upd05074.bin and was able to download the
UPD05074.bin version and tried that. I did get a different message that stated "Unable to install software in this vehicle"
I suspect that BMW has a glitch on their site with the VIN entry as described in the response from Connected Drive that I posted from another site.
BTW, the link provided will work for any valid software .bin version.
