ROBOTC Support - Troubleshooting


ROBOTC/NXT Driver crash issue




We have worked with National Instruments to solve the new NXT driver issue causing ROBOTC to crash. It was because the installers did not have all of the dependencies required to properly use the fantom.DLL communication library.

We have a released a new Driver to fix this issue.

Steps to fix the issue:

Step 1:

Download and Install the latest NXT LEGO USB Driver:


Step 2:

Make sure you are running ROBOTC 3.02 or later.


This should solve the issue. Thanks for everyone's patience in working with this problem.
