Hi, I just got a CTC 2nd generation (I think - black paint over wood body). When I run ReplicatorG-0040-Installer.exe all is OK untill it reaches Device Driver Installation Wizzard.

Then the following drivers won’t install with the messages as below.

ArduinoLLC(www.arduino)(usbser) Ports (11/15/2007 5.1.2600) Install Failed.

MakerBot Industries (usbser) Ports (11/15/2007 5.1.2600) Install Failed.

MakerBot Industries (usbser) Ports (11/15/2007 5.1.2600) Install Failed.

When I run the ReplicatorG program I then get the following:-

[10:49:35] C:\Users\bobgp\Desktop\Manuals\3D Printer\T-RexSkull_Luxo.stl
[10:49:35] Got name Default
[10:49:37] Parsed object name[Default] facets 293162
[10:49:39] Connecting to machine using serial port: COM3
[10:49:39] Motherboard firmware v7.4 ()

[10:49:39] You are running an unverified MightyBoard,
[10:49:39] your machine is not a verified MakerBot Replicator
[10:49:49] Network unavailable or update site timed out.

Any help would be most welcome.

I would suggest you to refer to the user manual of your 3D printer which contains all the information relating the software installation etc.
