Yes, silent installations are quite possible and commonly used with SMS. The key is to find out exactly how the silent install is configured. Many software packages support a -s or /s parameter which will allow for a silent install. (Example: Setup.exe /s) You may also have to create a configuation file that is used by the installation setup program to assign all the software package parameters. (Example: setup.iss)Also, some software companies are kind enough to create .SMS and .PDF files which are preconfigured SMS Package template files. Use .SMS and .PDF files when ever possible. Silent installations will take some investigation and time, but it will be worth the research.
