Typing ". file" at a bash prompt means "read the file and execute the
commands stored within", which means bash will open the file and try to
execute its contents as if you'd typed them at the prompt.  That is NOT
what you want for an .EXE file, it only works for shell scripts.  To run
a normal executable you just give its name and bash runs it.  In the
case of an executable in the current directory, this is normally not in
the path and so you need to specify "./file" to tell bash to look in the
current directory which is ".".  Those are two completely different uses
of "." though.
