Mass install ADE while user is not logged in

I am trying to do a mass install of ADE at my school with PDQ deploy. I am running this with a powershell script and it successfully does this if, and only if, the user is logged in to the computer. I will paste my script below. I have used PDQ to install software across multiple machines before without an issue. This is leading me to think that maybe I am missing something with ADE that is preventing it from working. I appreciate any help you can provide : D

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\N360" /v nss /t REG_DWORD /d 2 /f
