Unity 4 Linux build doesn't launch - failed to load mono

Unity Engine

I made a Linux 32/64 build for my game but received at least two messages from users that it doesn’t run.

Error (Ubuntu12.04_64bit):

nawb@master:~/Desktop/sl$ chmod +x Sacred_Line_1.2_Overhaul.x86_64
nawb@master:~/Desktop/sl$ ./Sacred_Line_1.2_Overhaul.x86_64
 Set current directory to /home/nawb/Desktop/sl
 Found path: /home/nawb/Desktop/sl/Sacred_Line_1.2_Overhaul.x86_64
 Unable to load mono library from /home/nawb/Desktop/sl/Sacred_Line_1.2_Overhaul_Data/Mono (x86_64)
 Failed to load mono

Maybe somebody knows the solution?

Raised the topic to the page 1.
Nothing about that in Google and forum search.
Maybe someone experienced the same error?

Bump.

I am certainly having this same issue…and I guess you haven’t fixed it since you haven’t replied to your own thread with a fix.

I’m just going to note that I played around with the build and got it to magically work. It seems that for me, the thing wouldn’t run if I built it as just x86 or x64, but when I did an x86/64 build and ran the x86_64 one, it didn’t encounter the mono error.

Ubuntu LTS (12.04) with Unity 4.1.0f4 on Mac OSX 10.8.2 (Mountain Lion).
