    • The Replicator properties 1.4
    • Driver tab 1.5

    If you’re using your MakerBot Replicator on Windows, you’ll need to install a driver.  The “installer” version of ReplicatorG will try to do that automatically, and you’ll only need these directions if it fails, or if you’re doing a manual installation.

    To get started, plug in The Replicator and turn it on.  Make sure that you’ve already installed ReplicatorG.  You might see a message about the driver installation. 1.1

    To properly install the drivers, you’ll need to go to the Device Manager.  This is located in different places in some versions of Windows, but on Windows 7, you can find it by right-clicking on “Computer” in the Start Menu and then choosing “Properties." 1.2

    Next, you’ll see the “System Properties” page.  Click on “Device Manager” in the upper left.1.3

    You should see a yellow exclamation point next to The Replicator.  Double-click it to open the properties. 1.4

    Now navigate to the “Driver” tab.  Here you’ll want to click on “Update Driver.” 1.5

    On the next screen, choose “Browse My Computer.” 1.6

    Another screen will pop up now where you’ll click a button labeled “Browse.”1.7

    Now navigate to where you’ve installed ReplicatorG.  The drivers will be located in a subfolder called “Drivers.”  Select it and hit OK. 1.8

    Windows will tell you that the driver software isn’t “verified,” and ask you whether you want to install it anyway.  You do. Choose “Install this software anyway.”1.9

    After a few moments, you should see a screen like 1.10

    If you see a message like this that refers to either the “MightyBoard” or “Replicator” you’re all set.  You should see a new COM port in the “Connection (serial port)” menu next time you open ReplicatorG. Choose that, as well as the appropriate Replicator machine type, and you should be good to go.
