If you've extracted the archive correctly, you have following files in your raft game directory:
V1.05b_Raft_Win64_Data (folder containing all the game's data files)
ReadMe.txt
V1.05b_Raft_Win64.exe
If app.info and other data files are in the same folder as the executable (they need to be in the V1.05b_Raft_Win64_Data folder), you've extracted the archive wrong.
