CADLock 3.36 fully supports all variants of the AutoCAD releases shown below, where those variants began shipping before September 2005. This includes vertical market applications (e.g. Architectural Desktop), and AutoCAD software to which Service Packs have been applied, where those Service Packs were released before September 2005.
If you are unsure about support for your specific AutoCAD variant, you can check for yourself by downloading and running CADLock RT. If CADLock RT runs with your AutoCAD variant, then the same version of CADLock SE should run too.
