Endpoint Manager Install Issue

I am trying to install EPM from module admin. I confirm I want to do so, and the status box opens but never shows any progress with the install. I have waited up to an hour. Also each time it will kill Apache. I have to go into CLI and do a httpd restart to get the GUI back. Running distro 5.211.65-8, Asterisk 11. I do have a valid license. Not sure how to troubleshoot it. Thanks in advance.
