You receive an error message if you change the "Shared component directory" path on the Feature Selection screen when you install SQL Server 2008 on a computer that is running an Itanium-based version of Windows
You try to install Microsoft SQL Server 2008 on a computer that is running an Itanium-based (IA-64) version of Windows. However, if you change the path in the Shared component directory box on the Feature Selection screen of the Install SQL Server 2008 Setup wizard, you receive the following error message when you click Next:
The INSTANCESHAREDWOWDIR command line value was not specified.
This problem occurs because the Install SQL Server 2008 Setup wizard does not let you specify the InstallSharedWowDir folder path. This path is required to install shared components in the SQL Server 2008 installation. You can only specify the InstallSharedDir folder path.
Note For more information about the INSTALLSHAREDDIR parameter and the INSTALLSHAREDWOWDIR parameter, see the "More Information" section.
To work around this problem, use one of the following methods.
Method 1: Use the default path
If you can use the default path for the shared components, do not change the path in the Shared component directory box on the Feature Selection screen of the Install SQL Server 2008 Setup wizard. If you change the path, you will receive the error message that is specified in the "Symptoms" section. If this occurs, click Cancel, and then restart the SQL Server 2008 installation.
Method 2: Use the /INSTALLSHAREDWOWDIRsetup parameter
If you have to specify a different folder location for the shared components, follow these steps:
Start the SQL Server 2008 installation by using the /INSTALLSHAREDWOWDIR parameter at the command prompt. The /INSTALLSHAREDWOWDIR parameter specifies the location to install the 32-bit shared component files.
On the Feature Selection screen, specify the folder to install the 64-bit shared component files in the Shared component directory box.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
When you install SQL Server 2008 on a computer that is running a 64-bit version of Windows, shared component files are installed by setup parameters into two separate default folders, as listed in the following table:
Program Files\Microsoft SQL Server
64-bit shared component files
Program Files(x86)\Microsoft SQL Server
32-bit shared component files
For more information about these and other setup parameters for the SQL Server installation, see the SQL Server Setup Help (S10ch_setup.chm) file. The S10ch_setup.chm Help file is located in the following folder of the SQL Server 2008 DVD:
