[Gretl-users] Gretl Installation Failed

Good morning, I am trying to download GRETL for MacOS with Intel Processor. I follow all the proceedings and suggestions given but any time I try to download it, it tells me ''The installation Failed" and to contact the software manufacturer. There's still capacity to support the installation of Gretl on the disk. I tried to figure out why but I can't understand. I got a Macbook Pro 2017 version 13.2.1, I would be glad if any of you may help me. Thank you again, best regards
