perl imscp-autoinstall -d not work (1.2.4)

On Debian 8.0

I'm trying to do an installation from 0, but the pitcher does not work, he never had problems.

the file is empty imscp-autoinstall

-rwxr-xr-x 1 root root 0 jun 12 03:28 imscp-autoinstall

I downloaded the new zip 1.2.4 and uncompressed and this time it works
