Well i started looking at this thread: http://www.msfn.org/board/index.php?showto...ega+codecs+pack for installing Ace Mega unattended but as somebody noticed there this way not everything gets installed. Looking into the problem one would notice that the components line (in the generated inf file) ends abruptly with an comma wich would suggest something should follow and that there are only codecs there, no bsplayer, filters or utilities. So I created a second inf file with no codecs and in that file I obtained only filters (entries like filters\blah_blah). Long story short the /SAVEINF AND the /LOADINF file truncates that line and not all components are installed... Further you can make the file shorter by specifing just the top entry and not all entries (ie only codecs instead of an entry for each codec). I attach two inf files with wich you can make a full install without media player classic, antivir, Real Media filters (not codecs), Flash filters, Quick time filters. I removed the later beacuase the installer would ask me for firefox's install dir. Oh there are two files beacause the /LOADINF also truncates the line you should run in your scripts (don't forget to modify the install path in them) start /wait ACE6.0.3Pro.exe /LOADINF=part1.inf /VERYSILENT /SUPPRESSMSGBOXES start /wait ACE6.0.3Pro.exe /LOADINF=part2.inf /VERYSILENT /SUPPRESSMSGBOXES PS if you want bsplayer out just delete "bsplayer," from the first inf file. Also I'll post a bit later some scripts for RunOnceEx.cmd which will install ace mega in the default Program Files dir part1.inf part2.inf
