how to be able to play steam and sendowl versions on the same machine

[Bludragon]

So, i decided to connect my game to Steam, thinking I should be able to keep the sendowl version to play (love BaconBits' mods but they're not on steam afaik).
The only problem is now when i install the sendowl download it has the steam api in it. I have created a seperate folder under a different file name to do this but it's not working for me. Could somebody please tell me what i need to do to make it work? I have read some posts that suggest it's possible, but the info is directed at someone who knows more than I do.
