RS won't install

[BenH]

My System:
PIII 866, Win98SE, 256Mb, 33.5Gb free HD space.
DX 8.1 already installed. Jedi Knight I I: Outcast already installed.

When I try to install "Rogue Squadron" the install shield progress bar gets half-way then displays the following message:
<Setup is unable to decompress and copy all of the program files needed to proceed with the installation...
"Error 112">
Any ideas??

Hey you all, try finding out if the RS you've got can play under Windows 98SE. The version I've got will play under Windows 98SE but not under Windows XP or 2000. Try finding that out.
