OK friends, here's what you've been waiting for!... After completely disabling NAV 2003 (by disabling auto-protect, email scanning, script blocking and automatic LiveUpdate) and stopping related processes from loading at XP's startup, I was able to coax Emperor to load long enough so that Windows could generate a log of the error. I've attached that log file if anyone feels like ciphering through it to find out what is causing the problem (I was unable to do that). In the meanwhile, while browsing Westwood's FTP looking for maps, I found and downloaded EMPENGINSTFIX10.ZIP. This update fixed some compatibility issues between Emperor and certain makes of CD/DVD/CDR drives [the readme says]. Along with the readme, I also found a SETUP.EXE and EMPEROR.EXE within the zip file. Then I said to myself: what the heck, nothing else has fixed the problem ... why don't I try replacing my EMPEROR.EXE with the one in EMPENGINSTFIX10.ZIP and guess what ... EMPEROR: BATTLE FOR DUNE LOADED PERFECTLY!!! My next step was to enable all of NAV 2003 services and try Emperor, and again, Emperor loaded successfully. I have a feeling that this fixed EMPEROR.EXE is probably closely related to a NoCD fix, but Emperor still asked for the Atreides Disc when starting my Atreides campaign, so it's not quite a NoCD fix. I assume that the reason why some of you who did get Emperor to work with NAV 2003 are probably running the game with a NoCD/fixed EXE. Anyway, if you're having problems with Emperor: Battle for Dune and Norton AntiVirus 2003, just replace your EMPEROR.EXE with the one found in EMPENGINSTFIX10.ZIP and, hopefully, everything will be fine :) You can get EMPENGINSTFIX10.ZIP off Westwood's FTP: ftp://ftp.westwood.com/pub/emperor/update/EMPENGINSTFIX10.ZIP Enjoy everyone and thanks for all your help ;) [attachment archived by Gobalopper]
