Hi All, After reading several blogs, MSDN articles, and posts here on the community forums, I am asking for help with doing a quiet install of Sql Server 2008 R2 (with SP2) as one of the pre-reqs of my application. Here is what I have done so far: 1. added the pre req to the install project, making sure that all of the necessary pre reqs for Sql Server 2008R2 are added. 2. set the pre req install order to make sure the necessary pre reqs for Sql Server are installed first. 3. opened up the Sql Server pre req in the editor to set the command parms. Those parms are as follows: /QS /HIDECONSOLE="True" /ACTION=Install /IACCEPTSQLSERVERLICENSETERMS /FEATURES=SQLENGINE /INSTANCENAME=MSSQLSERVER /SECURITYMODE=SQL /SAPWD="**********" /TCPENABLED= 1 /SQLAUTOSTART=1 /AGTSVCACCOUNT="NT AUTHORITY\Network Service" ****************Additional information************************** Just to add to my original post, I have also tried the following parms for the silent install, but I am STILL getting the same result. /QS /Action=Install /Hideconsole /IACCEPTSQLSERVERLICENSETERMS /SkipRules=RebootRequiredCheck /FEATURES=SQLENGINE /InstanceName=MSSQLSERVER /AGTSVCACCOUNT="NT AUTHORITY\Network Service" /AGTSVCSTARTUPTYPE=Automatic /SQLSVCACCOUNT="NT AUTHORITY\Network Service" /ASSYSADMINACCOUNTS="NT AUTHORITY\Network Service" /SQLSYSADMINACCOUNTS="Builtin\Administrators" /BROWSERSVCSTARTUPTYPE=Automatic /SECURITYMODE=SQL /SAPWD=********* /ADDCURRENTUSERASSQLADMIN=True /TCPENABLED=1 ****************************************************************** Now, the pre req is recognized during the install and the Sql install is unpacked, but then the UI is displayed to the user. This is what I need to avoid! So What exactly am I missing or doing wrong here? I appreciate any and all responses to this! Thanks in advance, Eric ... View more
