When I try to launch the map editor it complains about not being able to find "tome.1" files but they are there, then suggests running setup.exe from the CD, which does not exist. How do I get the map editor working? Also, I did a search, but GOG forum gives me no results and changes my search replacing spaces with %20
Also, why the hell does GOG tell me "wrong file format" when I try up attach a screencapped image? WTF? I had to open these screencaps in an image editor and resave them. What, now one of the jpegs is still not attaching "wrong file format?"

Reinstall GOG Galaxy (or offline version) to X:\Games\. And even with that check on admin run checkbox in Galaxe (and\or game) exe.
Install game to X:\Games\. Check game files after downloading if it from Galaxy. Better twice (since GOG dont report result of verifying in first time). Make sure Galaxy starting as admin. Same for game exe (if started from galaxy it enough to start Galaxy as admin).

Map Editor not required this - if lauched not from program Files.

Tried this. I just recently reinstalled galaxy because it stopped working. I did a verify/repair twice, and each time started galaxy as admin, but any time I try to start the map editor from galaxy, or starting Warcraft II Map Editor.exe as admin from the folder, it gives the same message that it's missing tome.1, even though it's in the folder.
