I'm not sure how to test that, since it all works fine for everyone 
except those 3 people, and they aren't users we can actually ask to test 
for us.

But I did some searches and found several indirect references to the 
same problem in other languages (C#, php, java) and their "exists" 
functions also return false if the user doesn't have permission to 
access the file. I have to assume that's what's happening here too, it's 
the only explanation.

We've asked one user to move the app folder to the Documents folder, so 
we'll see how that goes. We think at least some of the affected users 
may be running on public computers, which are likely restricting 
permissions (which is why the app works on their thumb drives I guess.)

The surprising bit to me was that "there is a file" can return false, 
even if it's right there in front of you. I'd have thought that it would 
always return true, whether or not you could run it.
