The EXACT same file and installation on a different computer worked perfectly fine. Both are Windows 8.1. Any suggestions to get it working on the other (newer) laptop?
My Nexus 5 is recognized by BOTH laptops via adb by the way.
I think you need to turn off driver signature verification. .

No problem, I appreciate the help. I tried both USB ports already as well (I'm not one of those people who posts on the first failed attempt, I literally tried everything I know). I've also tried the universal ADB drivers, no help.
I'll check out your version of ADB, though I think it's something with the driver and/or installation process. It's just odd that my Nexus 5 connects to ADB fine.
