How to load .exe from key?? payload for passwords

[Phoenix75]

Hi to all, I've received some days ago my rubber ducky. I't working fine, but I'm unable to create a payload that executes files on the key. I've found some payloads for credential extraction that uses nirsoft softwares. I've used the script, compiled it and putted on the key. I've also copied all the executables in the root. It gives me every time error that doesn't found the executables. Maybe because there's no drive letter mounted? Is there a real way to use externa programs on the key? In particular i'm testing that script. Is it working in some manner? or for windows 10 there's something better? Sorry if some seems stupid questions but i'm new at all.
