How do I select the "Physical Robot"? Currently it is set for "Virtual World" and it won't allow me to change it.

Usually when we see this it is because that particular installation of ROBOTC does not have an active license or trial attached to it. If there is a Virtual World license (but not a ROBOTC license), you will be able to compile to a Virtual World but not to a physical robot.

Double check to make sure you have a valid ROBOTC license active; to do this, navigate to the 'Help -> Manage License' menu option in ROBOTC to check for a license. If you need to activate a new license, you can use the 'Add License' option to enter and activate your license on that computer. We also have a wiki page dedicated to setting up and activating ROBOTC that you may wish to look through.

Thanks, Our tech people were able to fix the installation problem.
