Since CANoe/CANalyzer 7.0 System Variables are supported as a successor of Environment Variables for configurations in CANoe and CANalyzer.
Starting from CANoe and CANalyzer 12 no more new Environment Variables can be created in CANdb++ Editor.
It is still possible to use existing configurations and database files which contain Environment Variables. But it is recommended to use System Variables instead.
If you need to convert your environment variable into a system variable, please feel free to contact Vector support.
