The bin4ry method
doesn't even detect the device without some initial work.
When the device is plugged in, Windows detects the MTP drivers but not the MT65XX drivers which I believe is needed for Android ADB.
You can download the MT65XX drivers from the link below
After installing these drivers the Bin4ry root will detect the device but it will get stuck in one of the steps.
Maybe a newer version of Bin4ry will work or someone can figure out how to get it to work.
No longer need this driver, just read "New Acer Drivers" post below
