------- Additional Comments From saulius.krasuckas@elst.vtu.lt 2007-28-05 18:26 ------- Setup process finished here successfully, but warning message box did appear for me, too.
BTW, Ben, is sound working on your linux box?
Now I remembered similar thing was happening to me with the same symptoms when my RH8->FC6 upgraded box was starting-up without appropriate ALSA kernel drivers support.
Plus I've tried installation on WinME just now. It fails immediately with error msgbox about "Insufficient privilegies to install this app." and then some warning msgbox appears. The latter contains readable text also. Sound system is working on WinME.
Looks same as your issue, except the game's error handler is probably not finding its string resources.
But, well, sound system wasn't working in my WinXP (XP has no drivers for my old ISA card), where ArmA made no complaints and was ready to install.
May that be combined sound + privilegies issue (maybe NtQuerySecurityObject related) ?
