in php_errors I noticed the error
[23-Aug-2022 07:36:25 UTC] PHP Fatal error: Uncaught Error: Cannot use object of type SplFileInfo as array in C:\CRM\www\suitecrm\include\utils\file_utils.php:57
so I found this problem on the forum
and I fixed the Upgrade Wizard installing the patch of the 7.11.14 release
and I get the Wizard working.
Thank you
Now I try to upgrade
