About the App Cache Management

Know-how Apps Components requires a runtime cache for its resources (xml files, process dlls, .CATNls, .CATRsc and icons).

This cache must be writeable to the user launching Know-how Apps Components and needs to be added to the environment path. The installation process now creates this runtime view automatically, in a location chosen during installation. It must be preserved from corruption because it cannot be created again by the runtime and must be regenerated with the installation procedure.

The fact that the runtime view is now created during installation has three consequences:

  • If the option to create a runtime view for Know-how Apps Components is chosen during the installation, the runtime view is no longer created when first launching a user app requiring the cache to exist, but is created before the 3DExperience Platform first run.
  • If the option is not selected during the installation, no Know-how Apps Components runtime view can be created later. The install process must be restarted (at least to create this runtime view).
  • If the runtime view is removed or corrupted after the installation, the Know-how Apps Components runtime cannot be fixed and the installation process must be restarted.
