Thank you for those screens. That wasn't the issue, sorry I should have been clear, it's when I've got the files, they are in .exe format and when trying to extract them (I presume that's what you're meant to do with them) that's when I get the error saying my laptop can execute the files.
I will probably give up on it now as it's a bit of a hassle getting extra content and deal breaker if I am only limited to the KN6500 styles as I really like the styles of the previous series. My dad had a KN5000 and really liked those styles. I may end up trading it for something else.
Thanks for your help and all the best,
Danny
