     Install Instructions

    If you installed the SCT device updater before you plugged the device in then this should be easy to fix.

    With your device connected:

    Open your computers Device Manager.

    Look for a device that is not installed like one with a yellow exclamation mark. (Here is a screenshot of what you are looking for.)

    If you see this, right click it and select update driver.

    A new window should open up and give you the option to either automatically search, or browse for files.

    Click browse for files

    Navigate to the folder you downloaded, and select “Open”.

    If you did this correctly, it’ll tell you your drivers have successfully been updated and once you click “OK” you should see something similar to the picture below.

    Now your communication should work between the device and the computer. With most devices, you will want to unplug it and plug it back in and restart the device updater. Then click “Display Device Settings and Serial” and if the serial number shows up, it is communicating.
