# Uninstall
Simplygon is uninstalled by using the Uninstall.exe
found in the Simplygon installation directory that defaults to %PROGRAMFILES%\Simplyon\9
but can also
be a different directory depending if Simplygon was configured using the advanced setup method.
Simplygon installer will detect if the same version or older version is already installed and in that case show an uninstall button instead of an install button.
A headless Simplygon uninstall can be done by providing switches /uninstall
and /quiet
to the installer as shown in example below.
> Start-Process .\Uninstall.exe -ArgumentList "/uninstall","/quiet" -Wait
