Expansion Explorer

[Stitch26]

I've gone to the 'Yamaha Music Europe' website to download the Expansion Explorer, only to discover that both the Mac OS and the Windows options are both the same. i.e. both Mac OS files. Yet, other people have succesfully downloaded the Window's version. I don't understand why I seem to have this problem?
Yes I double checked that I clicked the appropriate button. Both sets files are the same, I'm confused.
Has any one else encountered this problem?
