Information for users with CANalyzer 3.0,3.1,3.2, 4.0, 4.1SP1 Fatal Error CAN driver stub: CAN driver not found ...receive this when you are running CANalyzer 3.0,3.1,3.2,4.0,4.1SP1 on LAPcan? In the directory where you have installed CANalyzer (typically): C:\Program Files\CANalyzer\exec32\Batch ..you find a number och bat-files for using different hardwares with CANalyzer. Double click VCncrd32.bat for using it with our hardware (KVASER). Still doesn't work ? Please install our conflicting drivers, click here for detailed instructions.   Information for users with CANalyzer 4.1 SP2 or later Fatal Error CAN driver stub: CAN driver not found ...receive this when you are running CANalyzer/CANoe 4.1 SP2 or later? In the directory where you have installed CANalyzer/CANoe (typically): C:\Program Files\CANalyzer\exec32\Batch C:\Program Files\CANoe\exec32\Batch ..you find a number och bat-files for using different hardwares with CANalyzer/CANoe. Execute kvaser.bat for using it with our hardware (KVASER). Execute VCncrd32.bat for using it with VECTOR´s hardware. Execute VCncrd32.bat for using it our conflicting drivers (ONLY WORKS WITH LAPcan!) (You can not reach Vector´s hardware and KVASER hardware at the same time, sorry! In CANalyzer/CANoe it is impossible to use hardwares from different vendors in the same computer at the same time.  The problem is that if you have executed the kvaser.bat (as described) CANalyzer/CANoe will ONLY look for licenses on KVASER hardwares and ignore licenses on all other vendor´s hardwares, for example Vector CANcardX, even if the drivers are installed properly and properly inserted into the computer (and if the license is on the LAPcan card you can not see the license if CANalyzer is configured to work with Vector hardware)  ...and try to start CANalyzer again. Still doesn't work with our hardware? 1. Control Panel -> CAN Hardware (KVASER).  2. Expand (click the +) to the left of the hardware that you want to use with CANalyzer.  3. Assign the hardware, using the "Assign to application" button to CANalyzer or CANoe. (Assigning hardware is explained in the CANalyzer Installation guide) Still doesn't work?
