What files are needed to run a built game on a computer that doesn't have unity

I have compiled and sent off the data file and the exe file. when i down load them on a computer that does not have unity it wont run. says the mono dll is the problem.

any ideas on the issue or the fix would be appricated greatly.

thank you

The answer is none. Unity games are self-contained.

You just need to filebuild settingsbuild

They are not self contained by any definition I know of “self contained”. AFAIK the files you need are

YourApp.exe
YourApp_Data (a folder with lots of files)
MonoBleedingEdge (a folder with lots of files)
UnityCrashHander64.exe
UnityPlayer.dll

All of those files are put in whatever folder you designate as the “build” folder so zip up that folder and all the files needed should be inside.
