Run the installer from a batch file with the following command line:
/QS /ACTION=Install /FEATURES=SQLEngine /INSTANCEID=ABC123 /INSTANCENAME=ABC123 /SECURITYMODE=SQL /SAPWD=ABC123 /SQLSVCACCOUNT="NT AUTHORITY\SYSTEM" /SQLSVCSTARTUPTYPE=Automatic /TCPENABLED=1 /SQLSYSADMINACCOUNTS="BUILTIN\ADMINISTRATORS
The installer simply disappears part way through and the SqlSetup.log file reports that "Setup closed with exit code: 0x84C40013."
We also tested with a /Q switch and with the "WithTools" installer with the same results.
Operating System: Windows 7 Ultimate N Version 6.1 (build 7600)
Platform: both x86 and x64
We believe this is related to bug "SQL Server 2008 R2 CTP2 could not be installed on Windows 7 server RTM successfully" because if we run our batch file with neither a /Q nor a /QS switch, the installer fails with the error message:
"SQL Sever Setup failure: SQL Server Setup has encountered the following error:
Invoke or BeginInvoke cannot be called on a control until the window handle has been created."
