NXTCommException: Cannot load NXTComm driver

Postby matt.tau » Sun Jan 26, 2014 1:23 pm

I've tried to install leJOS on a brand new Win7-64bit (no other software installed by me) installation on a new Fujitsu-Laptop:
1. Setup 32-bit java (jdk-7u51-windows-i586.exe)
2. Setup the latest Fantom-Driver (LEGO_NXT_Driver_64)
3. Setup leJOS (leJOS_NXJ_0.9.1beta-3_win32_setup.exe)

Plugging-in my NXT-Brick, the device manager says 'LEGO Devices, LEGO MINDSTORMS NXT'

But flashing the NXT-Brick I get:
Bad news: An error occurred
lejos.pc.com.NXTCommException: Cannot load NXTComm driver

On other Machines I've never got this error.

I fixed this problem by replacing the actual Fantom-Driver by an older one from the official Mindstorms-CD v.1.1

Where did you download the fantom driver? From here?
http://www.lego.com/en-us/mindstorms/do ... om-driver/

If there is some version out there that doesn't work with leJOS (for whatever reason), please let us know which version that was.
