Simplify installer execution - remove overly strict checks

Removed the -x check that was failing despite file being executable.
Changed to simple file existence and size validation instead.
Back to direct execution (./ ) instead of bash wrapper.

The file shows -rwxr-xr-x so it has execute permissions.
The issue was the test itself, not the permissions.
