This dll is normally there, so maybe your AV quarantined it and corrupted the whole thing. ..or..Are you running the game directly from the RAR archive? Why? Makes no sense.Can anyone help me? The game won't start because it says the UnityPlayer.dll file is missing from the RAR package. I tried installing it myself, but it still doesn't work. If anyone knows how to get the game to start, or has a fully functional RAR file to download, please let me know.
Maybe also update your archiving software. I'm getting a little tired of people always blaming others when the problem is in their PC..
