"Error 42 (IPM)" when launching ROBOTC after installing ROBOTC Solution This error is caused when Windows XP or Windows VISTA does not have the appropriate rights to initialize the activation software. To fix this issue, you will need to run the application "As an Administrator." Once you have followed these steps once, you can use ROBOTC as a normal user (without Administrative Privileges) without issue. Windows VISTA Step 1: Right Click on the ROBOTC icon. Select "Run as Administrator" Step 2: Windows VISTA will prompt you to give Administrative Access to this application. Select "Allow" to continue. ROBOTC should now open to the Licensing Screen. You will not have to repeat these steps again to use ROBOTC in the future.
