A remote install has nobody sitting at the PC to click Next. The silent switch is what turns an interactive installer into a command the agent can run alone — get it wrong and the deployment hangs forever waiting for a click that never comes.
Every failed first deployment has the same root cause: the installer opened a window on a PC with nobody logged in to see it, and waited. Silent switches exist so that never happens — but EXE and MSI installers speak different languages, and guessing the wrong one is worse than not deploying at all. Here is the honest map of which switch belongs to which installer family, and how to discover the right one instead of copying random commands from forums.
MSI packages are the easy case because Windows Installer defines the switches. The pattern never changes:
msiexec /i "package.msi" /qn /norestart — /i installs, /qn means no user interface at all, /norestart stops a surprise rebootALLUSERS=1 — Endpoint Central's package screen has an Arguments to MSI field for exactly this/l*v "C:\install.log" while testing locally; the log tells you the real reason when an install fails with a bare error codemsiexec /x "package.msi" /qn /norestart or the product code in bracesThis is the part vendors rarely say out loud: an EXE installer can use any switches its author chose. The common families are:
/quiet /norestart or /silent/VERYSILENT /NORESTART/S — capital S, and it is case-sensitive/s together with a recorded answer file, covered in the next stepClassic InstallShield setups ignore simple switches because their questions are custom. The documented workaround is to record your answers once on a test PC and replay them everywhere:
Setup.exe /r /f1"C:\silentinstall.iss" and answer the setup normally — your clicks are saved into the ISS fileSetup.exe /s /f1"silentinstall.iss" and include the ISS file with the packageHonest discovery beats forum folklore:
/? or --help on a test PC — many installers print their supported switchesSome old or poorly built installers cannot run silently at all. The professional options are: deploy with a scripted automation tool such as AutoIt that clicks through the recorded steps (ManageEngine documents this route), ask the vendor for an MSI or enterprise package, or install that one application by hand and move on. What you should never do is deploy an interactive installer to fifty PCs and hope — you will get fifty PCs stuck on a Next button and a helpdesk queue to match.

No. /qn belongs to msiexec and MSI files. /quiet is used by many EXE bootstrapper installers and by Windows Update style packages. Using MSI switches on an EXE (or EXE switches on an MSI) is the most common silent-install mistake.
Yes, if you know its silent command line — ManageEngine confirms patches can be deployed as packages. For Windows and application patches, though, Endpoint Central's dedicated patch management does the scanning and approval work for you, which is usually the better route.
