It likely works on 2000 and newer. The "failure" is likely a version check that prevents it from running because of features and changes that require a newer version of Windows to work properly. If anyone absolutely cannot upgrade their Windows from 98, they still can use 6.35.
Well it works will with 6.35, i dont see why it cant work with win 98 :\.
It is a major rewrite from 6.35. Just because that version works on 98 doesn't mean this one will.
