Weird, I used this one (top one for the 3010)
Installed on Win 7 x86
First step showed where it would go, which was C:\Xerox\Phaser_3010__32
And when I browsed to it from the Windows installer it was exactly where it said it would be
And it will only list the one device when you choose it.
Now if you had thought the driver would just be on this screen, that isn't how it works, this screen shows currently installed to the system drivers, either ones that have already been installed before, or ones that came with Windows itself, it does not list drivers that are just sitting in a folder waiting to be installed.
