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.
There is also possiblity to do a headless Simplygon uninstall by providing switches
/quiet to the installer as shown in example below.
> Start-Process .\Uninstall.exe -ArgumentList "/uninstall","/quiet" -Wait
