This is a known issue with versions of ROBOTC that use License Files (.lf) to dictate expiration dates. The error occurs with Windows 7 and Windows VISTA not being able to initialize the license file without administrator privileges. Once the license file is initialized, ROBOTC works as expected and does not required Administrative rights.
The solution to this error is as follows:
"You may need to run ROBOTC as an Administrator for the first time in order to activate the license. To do this, right click on the ROBOTC for Cortex icon and select "Run as Administrator". Once the software is activated, you will not need to do this again."
If you download the latest BEST version - 2.25 - available at http://www.robotc.net/best/
- this issue will not occur as it does not rely on the license file.
