To make it work, follow these steps:
INSTALLING ROBOLAB
download the Robolab add-on by clicking here
download the installer by clicking here
Open the installer in LabVIEW for LEGO Mindstorms (this will only work if the installer and the zip file are in the same folder - the installer will unzip the zip file).
Go through the install steps (should start running automatically - this takes a while as it has to recompile everything)
Close all windows and restart LabVIEW
Go to the Tools menu and select Robolab 2.9.4d...
RUNNING ROBOLAB
