Abbreviating the Installation Procedure
To automatically run the windows that normally require user action, you can use the optional QR parameter. If you use it, then the InvisibleSSOModule.msi installation package does not display dialog boxes that require user action. This option is not available starting with Siebel CRM Desktop version 3.7. CRM Desktop SSO comes predefined starting with these versions.
To abbreviate the installation procedure
Append the QR parameter to the msiexec command.
For example:
msiexec.exe /I InvisibleSSOModule.msi INSTALLDIR=c:\My_Custom_Directory /QR
