To install the FULL-REGISTERED version of QUAKE from the Shareware CD-ROM:
  From within Windows or Windows'95...
    1. Install idSTUFF to default directory (do NOT install Shareware Quake).
    2. Run the UNLOCK and let it generate the first code.
    3. Open a DOS session and copy the QCRACK.EXE to the IDSTUFF directory.
    4. From the IDSTUFF directory, type QCRACK Q12345678901 (where Q1234567901
       is the code that ID generates). QCRACK will generate a key number.
    5. Go back to the UNLOCK and type in the key that QCRACK generated.

To install the OTHER FULL-REGISTERED games from the Shareware CD-ROM:
  From within Windows or Windows'95...

    3. Open a DOS session and copy the QCRACK.EXE to the IDSTUFF directory.
    4. From the IDSTUFF directory, type QCRACK -g FINALDOS Q12345678901
       (where Q1234567901 is the code that ID generates and FINALDOS is
       whatever game your are attempting to install).
    5. Go back to the UNLOCK and type in the key that QCRACK generated.
