Make sure you have ...

error_reporting(-1); // show ALL errors/warnings/notices/etc.

and ...

exec($Command, $Output, $Status); // Capture the output.
echo "The $Command returned a status of $Status and the following
output:", PHP_EOL, implode(PHP_EOL, $Output), PHP_EOL;

sort of thing.

The error may be in the zip.
