The game is Divinity: Original sin
I was missing a few of the libraries it needs to run, one of which was libicuuc.so.54. I tried to update libicuuc but the version installed was .55, and the game doesn't detect it.
./EoCApp: error while loading shared libraries: libicuuc.so.54: cannot open shared object file: No such file or directory
How do I get the proper version of libicuuc installed or force the game to use the newer version?
