Sophos setup (Silent) in a PowerShell (Windows 10) hangs

Hi ITService_Berlin,

Thanks for reaching out to the Sophos Community Forum. 

May I ask why you have the "-Wait" argument at the end of the command? Is this necessary for the script to run as expected? 

Hello, I am also running into this situation.  I want to add /wait to my script because in the past when I installed Sophos, it was very dependent on restarting.  In MDT, the installer would restart unprompted with silent commands.  The current installer doesn't prompt for a restart so I am wanting to "wait" until the process is done and restart. I am not currently using MDT for imaging, but I am deploying through remote software. 

Does the current installer need to be restarted?

A restart is encouraged but not required.  Reason being, the solution injects modules such as SophosED.DLL and Hmplaert.DLL into processes as they launch in order for some of the protection layers to fully function.  Mainly exploit mitigation.

For the processes already running, the modules therefore aren't loaded so this is the main reason.

Realtime-scanning, behavioural, Cryptoguard are all fine.
