haha... oops... my bad !
yeah.... some games are not 64_bit aware... they were made before AMD64 was so popular, so the way they work, is they run a "uname -a" and look for a list of supported porcessors (i386 i486 i586 i686 x86) and if they dont find one they like, they quit, even though AMD64 is backwards compatable with x86.
you need to fool the installer into thinking you are using a 32bit OS.
make sure that 1... your distro's 32bit compatability libraries are installed, then re-run the game uinsstaller with the linux32 command...
Code:
linux32 /path/to/executable
reand "man linux32" for more info...
i had to use this to install UT2003 from the game disks.
