Unable to downgrade to 1.11b or anything

[Lando]

I bought the Battlechest and its pre-loaded with v1.12, is there anyway to downgrade the version? I've tried adding 1.07 game.exe but then it asked for me to insert Lod CD so I am haven no luck here. Any suggestions?

No need to downgrade, CE delivers all needed files and switches beside your recent lod version, and the needed version for CE Mod
