I can't install some games/programs on FAT32 partitions. This bug (Can't create a file) doesn't appear when I install applications on EXT3 partition. For example this bug shows in installers of: Operation Flashpoint Resistance, Colin McRae Rally 2. Installer of Operation Flashpoint Resistance show bug when it try to copy file: A02Vulcan.ABEL.pbo (sometimes shows a bug on other files o.O).
Are you able to create files and directories, write to files as an ordinary user in Linux applications to your FAT partition?
