Acer C120 Windows 8 How To

I recently purchased an Acer C120 pico projector for reasons I’m not entirely sure of, but I found – along with a few others on the ol’ internet that it doesn’t seem to be compatible with Windows 8/8.1 when using USB 3.0 meaning you have to resort to a USB 2.0 connection.

The errors I was getting included the 3 discs randomly connecting and disconnecting, the autoplay program running but being greeted by an error about DLCapAPI.dll not being installed on the system so the program cannot run, or that the drive the program is meant to run from simply does not exist anymore.

The issue with this is that more laptops are shipping with USB 3.0 ports and Windows 8.1 meaning the advice Acer give to “try a USB 2.0 port” is pretty redundant. However there is a simple, yet moderately elegant solution to this whole problem.

The Fix

What you need is a USB extension cable, the type you get with Wireless USB headsets etc, or the USB plugs that cooling pads use to grab power but also let you connect a device still. Essentially to get the projector to work you need to use one of these cables with the MAIN USB cable of the projector as these cables are generally not USB 3.0 compliant, you’re magically using USB 2.0 again, except in a USB 3.0 port and you can move the projector further, so that’s a plus too as the cable provided is quite short.

I’ve tested this on my laptop and MacBook Air running Windows 8.1 and it works on both perfectly, you can use the slave cable in any USB port as far as I’m aware however you may wish to test this yourself. Usually I have the power cable on hand for the extra brightness.

TL;DR – Use a USB extension cable to connect to the projectors MAIN cable, works like a charm.
