Создать ярлык на setup.exe и свойствах его прописать
setup.exe /Action=Install /INSTALLSHAREDDIR="C:\Program Files\Microsoft SQL Server" /INSTALLSHAREDWOWDIR="C:\Program Files (x86)\Microsoft SQL Server" /INSTANCEDIR="C:\Program Files\Microsoft SQL Server"
We had the INSTALLSAHREDWOWDIR even with default paths. Many installers, including Web Platform. Don't forget to specify INSTANCEDIR!
