pro is a “variant” of CANoe. The other available variants are pex and run. Each variant comprises a different scope of functional features as described in the products section of vector.com with pro offering the full range of features.
Since version 12.0 this variant is officially called CANoe pro and the term CANoe without addition specifies the software in general regardless of a specific feature set. In former versions there was the latent ambiguity that CANoe could mean the software in general or the “fully loaded” variant. It is now:
|Software variant||CANoe pro||CANoe pex||CANoe run|
CANalyzer uses the same naming convention already since earlier versions.
