Hi Python007,

If I'm not mistaken, there are more CAB's, like data2.cab, data3.cab etc., CD-sized (?) volumes of a large archive. Changing one file would mean recompressing all files after it, including those in volumes with higher numbering. This is complicated and may not be implemented in CAB archivers.
A good idea might be extracting all files from all volumes and then recompessing them, either into multiple volumes or into a single volume. For the latter, you might have to hack the installer script (see "ORCA"; search for it on this forum or at the Micro$oft site). (No, I don't have this game; only speculating.) Good luck!

The killerwale will not help him InstallShield cabinet files are AFAIK incompatible to MS cabinet files. If he uses i5comp (really the old version 5?) correct it would work. If not: Install the game, fish all registry keys and create a new installation with another setup tool (e. g. InnoSetup). This is the way I prefer to overcome those problems.

Sorry, yeah, you're right, I forgot about the two different kinds of CAB's: M$ and InstallShield...
By the way, I do it similarly but I don't bother with creating an installation tool. I just change the registry entries so that they point to the current directory (single dot), test if the game runs (if not, hack it ) and then archive the whole thing with RAR.
