Iam doing silent installations often on several Systems. I install the Microsoft SQL Server 2012 Management Studio Express with this command:
"SQLManagementStudio_x64_DEU.exe /ACTION=INSTALL /QUIET /IAcceptSQLServerLicenseTerms="True" /FEATURES=CONN,BC,SSMS /indicateprogress"
The installation will take almost an hour to finish. 
I never get error messages or so. The installation afterwards is fine.
Is there a way to speed up the installation process?
Thanks!
