Update on a couple of details:
@Sabian,
Thanks for the location, I've downloaded and then when I tried an install of the newly extracted msi (admittedly on the same computer) I got exactly the same issue. Of note though is that running /qf automatically brought up the same serial number and the same incorrectly spelled company name. Installing on another computer (freshly imaged) doesn't have those inputs already present under /qf. Next when I try using the transfrom (a new one) with /qr it gives an error of the serial number, displaying the entire serial.
@Sebastian
I've had a look through yours and it seems our issues could have the same origin. Looks like I may have to call customer support regarding the serial number as Sabian suggested in your thread.
The bit that gets me is when the same serial number is used in a manual install (or /qf) then it installs ok without any errors.
