Thank you!!!

But if you try to format it ExFAT and try to run it from there?

I think so yes.
Normally you don't experience this problem when you are running only OSX.
But when you are a "MashUp-person" running Win/*nix/OSX you see it it from time to time.
Case sensitivity has been around for a long time in the *nix world.

Hi,

SH3D is another software in the line of softwares that doesn't work with case sensitive file system.

If I try to run it from "Applications" I get an JRELoadError.
But if I copy "Sweet Home 3D.app" to an USB stick the software runs fine.

This isn't the first software where I have seen this ...
