# Basic headless installation

The Simplygon installer supports installing Simplygon on the command-line. By passing /? or /help to the executable from e.g. PowerShell, the available options are printed to the terminal.

> Start-Process .\SimplygonSDK_10.1.400.0.exe /help

It is recommended to run the installer using the Start-Process cmdlet (together with the -Wait parameter) in PowerShell. If -Wait is not used, the installer executable will return immediately which can cause the output from the installer to get scrambled or lost.

> Start-Process .\SimplygonSDK_10.1.400.0.exe -Wait

In the example below we are launching and waiting for a command-line based installation without Autodesk Maya plugins.

> Start-Process .\SimplygonSDK_10.1.400.0.exe -ArgumentList "/quiet","/nomayaplugins" -Wait
