Newfag here, I read all the instructions of installing Elona+ 1.71 and Elona+C 1.71 properly. Elona+ works without the custom but once I installed the custom, error happens.
This is what I did: I first install Elona+, then extract the Elona Custom in the Elona+ folder ,and then run ElonaC.exe instead of Elonaplus.exe. But this is what happens when I open it (and yes I tried running it as administrator). Any idea what went wrong?
