I downloaded the offline backup game installer, but it won't run on Windows 98. Is there a way to get the GOG version installed on Windows98? Alternatively I could try installing from CD and then copying the files from a GOG install? I think it is a shame that there isn't an easy way to install the game on an OS it would have worked on back in the day!

I installed the game from CD then copied the executable across from a windows 10 install. It seems to work, though there wasn't a video at the start of "The Iron Seed"
