For what it's worth -
I've tried for 2 - 4 hours now to get OrangeHRM installed on SME9.2 without success.
I was unable to find any combination of sockets, ports, php, or mysql versions that would allow the orangehrm installer to complete "normally" (NOTE: after any failed installation attempt, you need to clear your BROWSER cache before re-trying. I have never seen this in another web app installer...)
I was able to get OrangeHRM installed manually (create ibay, configure to use php71, customize php.ini for php71 to use mysql55 for both mysqli and pdo_mysql, configure mysql55 to use port 3306 in case the bug in the OHRM installer is related to the mysql port, create the database manually, load the tables and default data using OHRM/dbscripts/dbscript-1.sql and OHTM/dbscripts/dbscript-2.sql, create OHRM/lib/confs/Conf.php based on OHRM/lib/confs/Conf.php-distribution, insert the database details, then run the OHRM web updater) but that procedure leaves you with no user accounts, so you can't login (unless you write a custom php script to generate a password hash to insert manually into the user table).
Installer problems with OHRM go back to 2009, and the responses I saw from the devs look like "use the paid version".
My recommendation is to find an all-in-one installer rather than try to figure out how the apparently fragile and under-documented OHRM installer works.
Bitnami has the current version of orangehrm available in many formats.
