We have been doing the summer course for RobotC using the RobotC for Virtual Worlds. We wanted to try our virtual programming skills on an actual Cortex so we downloaded the trial version of the RobotC for Cortex version 3.61.1. When we tried to install it, we got a message that there was already a newer version of RobotC installed and we would have to uninstall it in order to finish the installation.

We don't want to uninstall the Virtual Worlds yet because we aren't done with the course yet. What I don't understand is that RobotC for the Virtual Worlds is version 3.61.1 as well. Has anyone else had this problem? Does anyone know what to do to fix this issue?

Hi SLic,
The secret is there's actually only one version of ROBOTC, and different parts are activated when you have licenses for them. To activate a 30-day free trial license for VEX Cortex, open ROBOTC and choose Help>>Manage Licenses from the menu. Click the Add License button, choose ROBOTC for VEX Cortex and PIC from the dropdown and click Start Trial. If you've purchased a license, you enter the LicenseID and Password, then click Activate Online.

To select VEX Cortex mode, choose Robot>>Compiler Target>>Physical Robot from the menu. You may need to select Robot>>Platform Type>>Innovation First (IFI)>>VEX 2.0 Cortex as well.

Cheers,
