Even though my installation of SCRM 7.1.1 completed without any errors or warnings, there is still an error in install.log. The error is pointing to a missing custom/install/install_hooks.php file that it required? After doing a full search for this file on the localhost I can confirm that it definitely does not exist.
What is the function of this file?
Does it contain any required configuration actions that may cause the environment to fail / become corrupt / miss any essential features?
