LispWorks looks for a valid license key when it is started up. If a problem occurs at this point, LispWorks exits
These are the possible problems:
On Linux and FreeBSD, this is also a possible cause of the problem:
On Mac OS X, Linux and FreeBSD, the key is expected to be stored in a keyfile, and an appropriate error message is printed at the terminal for each case. If this message does not help you to resolve the problem, report it to Lisp Support and include the terminal output.
On Windows, the key is expected to be stored in the Windows registry. If you cannot resolve the problem, export your HKEY_LOCAL_MACHINE\SOFTWARE\LispWorks registry tree and include this with your report to Lisp Support.
