So when I downloaded it it said the unityplayer.dll was missing when I can see it right next to it then it said the TentacleLocker_PC_1.0 was missing do you know what I should do.
Well we didn't get to test on 7 so not sure if that is it or not :/ Maybe this could help? https://answers.unity.com/questions/1425830/the-program-cant-start-because-unity...
