I think the only problem is the world editor’s seem to share the same registry. I have both reforge and the Original Disc Battle chest versions (you can get them still on amazon). I Started off with the Discs they work fine even the map editor, I updated it to 1.27b (everything else cause it to go to reforge). Once I did that I installed Reforge just to see if I could use both fully One on an External the other on my main drive. I can BUT only the Reforge Map Editor can Be used. If I try to bring up the old Map editor it loads up and CTD’s with out error. Uninstalling Reforge does nothing as you have to manually go into your registry and remove all Warcraft III related items (unless there on like Microsoft edge meaning a web search). If blizzard were to do what you suggest and I fully Support they need to ensure both games have separate Registry entry’s to prevent the issue I have found otherwise is useless.
