Should I rename it?
Strictly speaking, you don't need to rename it, the name doesn't matter.
It's just very weird that you have settings in "data" folder and actual data in a different folder. I think it confused everyone here, including myself.
Anyway, I think everything necessary has been said here already.
To run OXCE you need:
1. OXCE data files in folders "common" and "standard'
2. Original Xcom data files in folder "UFO"
3. and OXCE executable for debian 8... the one someone provided in a different thread
Put them together as they should be and it will work.
If you can't do that, wait for Knapsu's distribution, maybe it will be easier for you that way.
I'm just surprised, especially after seeing how well you have structured and documented your mod and even put it on github... that you have such problems with a few installation steps.
