10.2 License keys

LispWorks is protected against unauthorized copying and use by a simple key protection mechanism. LispWorks will not start up until it finds a file containing a valid key.

The image looks for a file lwlicense in the following places, in order:

• In the current working directory.
• In the directory containing the LispWorks executable.
• In the lib/8-0-0-0/config subdirectory of the LispWorks installation directory.

When the file lwlicense is found, it must contain a valid key for the current machine. If you try to run LispWorks without a valid key, a message will be printed reporting that no valid key was found, and LispWorks will exit.
