1. Sorry, I think we have a bit different lingo. I don't get what you mean by "pointing the MS-DOS exes to targets". Are you talking about a shortcut? Have you actually installed the mod, rather than moving the EB11.exe and EB12.exe somewhere?

2. Where have you installed RTW?
3. Where have you installed EB 1.1?
4. Where have you installed EB 1.2 (the answer to this question needs to be the same as the answer to the previous one)?
5. What precisely is your shortcut target?
