Hi, I've tried using your script, and it works beautifully! Except in situations where devcon asks if you want to overwrite old files, where it will pause, waiting for input. I decided to edit the script, adding to the If...Then...Else block, to take this new prompt into account. Upon running the script, I get: "Line -1: Error: Unknown option or bad parameter specified." I thought this was a problem with my edits, so I recompiled the .exe from your original DriverInstall.au3 file that you included, to get the same error! So I was wondering, what were the differences between that file and the one you originally compiled from? Or am I just having problems on my machine? Thanks in Advance, Adam
