Installation
Important notes:
UT4MOD Installation:
Simply open the file 'WoE.ut4mod' and click a few buttons.
If UT2004 has become disassociated from the .ut4mod extension (i.e. it doesn't know what program to use when you double-click on it) then you might want to try UT2Kx Regcheck.
Manual Installation:
If you would rather do a manual install, then you must first extract the files from the ut4mod. There is a utility available for this purpose, called 'UT2MODExtractor'.
Once that is done, copy the files into the appropriate directories in your UT2004 directory. Do not overwrite Manifest*.
