how to open a executable file from pendrive?

I am trying to open blender 2.79 dev build, but I get a dialog saying Failed to execute child process “/mnt/sdc1/MBD-Stuff/blender-2.79/blender” (No such file or directory). I tried another stable build and it opened, but I do not understand why the another did not do anything, or show the dialog. I am using fatdog 64 800 os.
