Win7 install cant find printer driver  

Win7 install cant find printer driver

Finishing up new MK3 build (first time 3d'er). I download the Windows software from support page (2.1.8 is current version) and run install.
I download the latest firmware (3.3.1) and unzip the .hex file to temp folder.
Now I am supposed to run Slicer to perform a firmware update. I hook up the usb cable from laptop to printer (printer is turned off). When I do this I see the little popup in bottom right of screen saying that Windows is looking for the device driver. Ultimately it will not find the driver. I have two Lenovo model laptops and get the same response. If I go to device manager I see Prusa i3 MK3 under the Other section, not under Ports where I think it is supposed to be. If I click on this device it shows that the driver not installed.

Rather frustrating is that in all the documentation online and in print I don't see any mention of this issue. I emailed [email protected] but have not gotten a response (surprise surprise).

Anyone experience this or have any ideas how to proceed? I have tried reinstalling the Windows app and having the printer turned on, tried having the usb already plugged in before installing app, tried running slicer as admin. Cant seem to get by this Windows not being able to find the printer driver.

Thanks all !
