Why won the v1.4 patch install correctly?
=================================================== The DOOM v1.666 patch expects to find the ORIGINAL game in your DOOM directory. If you replaced or altered the DOOM.EXE file with a new version, the patch will not work. If the patch complains about missing “LICENSE.DOC” and/or “FILE_ID.DIZ,” the command “PATCH -ignoremissing” can be used. However, this will not help if the patch complains about “DOOM.EXE” or “DOOM.WAD.” If you are using the registered version, some distributors shipped an older release of v1.1. It is recommended that you call your distributor, or E-mail “help@idsoftware.com” if you ordered from id Software for more help.
