For a Windows Server 2008 x64 Bit or Windows Server 2003 x64 Bit, the copy information is incorrect. SSMS and VS are 32 bit apps. So it needs to reference the x86 Program Files and NOT the plain Program Files which is x64.
Instead of
1. Copy the files, SEMSFC.DLL, SQLGUI.DLL, and SQLSVC.DLL, from the %ProgramFiles%\Microsoft SQL Server\80\Tools\Binn folder to the %ProgramFiles%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE folder.
2. Copy the files, SEMSFC.RLL, SQLGUI.RLL, and SQLSVC.RLL, from the %ProgramFiles%\Microsoft SQL Server\80\Tools\Binn\Resources folder to the %ProgramFiles%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Resources\%lang_id% folder. For example, for U.S. English, the lang_id subfolder will be "1033".
It needs to say:
1. Copy the files, SEMSFC.DLL, SQLGUI.DLL, and SQLSVC.DLL, from the C:\Program Files (x86)\Microsoft SQL Server\80\Tools\Binn folder to the C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE folder.
2. Copy the files, SEMSFC.RLL, SQLGUI.RLL, and SQLSVC.RLL, from the C:\Program Files (x86)\Microsoft SQL Server\80\Tools\Binn\Resources folder to the C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Resources\%lang_id% folder. For example, for U.S. English, the lang_id subfolder will be "1033".
