What Causes "No such file..." When There Is A File?

Question

I think I've seen this in the past, but I failed to record the solution. I did a forum search, but didn't turn up anything.
I've seen a couple of programs where, when you're in the folder, and you execute "./programname" Linux says: No such file or directory
And the program files have executable permissions, such as rwx rx rx

Yes, that would certainly fit. I thought I would get some other complaint for that. But I'm delighted to know the exact nature of the problem.
And I'm going to record something about it, so hopefully when it happens after I've forgotten it, I'll see the note.

If the program was originally dynamically linked, you'd be seeing 'Wrong ELF class' errors. That makes solving the problem much more simple because error usually points you in the right direction.
The simplest approach to solving this problem is to check the program's site, README file, Arch's AUR, etc, and looking for any dependencies. You won't need much to see it what it wants. For instance, if a site says that you 'only' need the binary and libstdc++5 to run and you're on a 64 bit system, just install lib32-libstdc++5. It may not be enough to make the program work, but the 'Wrong ELF class' errors will appear and point you in the right direction.
