Error: Microsoft SQL Server Shared Feature Directory (INSTALLSHAREDDIR, INSTALLSHAREDWOWDIR)


During an installation of Microsoft SQL Server 2008 R2 x64 Standard Edition on a Windows Server 2008 R2 Service Pack 1 x64 Standard Edition operating system, I encountered issues on the Feature Selection screen.

Issue #1 - While the installation is 64bit, the Shared Feature Directory is hard coded as x86 - this is wrong.

Issue #2 - Error:  "The INSTALLSHAREDWOWDIR command line value is not valid. Please ensure the specified path is valid and different than the INSTALLSHAREDDIR path."


Aside from the regular disclaimer about don't modify the registry unless you have backups and know what you are doing, I want to also mention that the solution that worked for me does not apply to all situations.  For example, if I experienced this issue while installing on an Itanium processor, then the solution would be different (Microsoft Support, 2011).

So, having said that, the solution for this particular situation was the following:

1.  Open the Registry Editor

2.  Export the following key (as a backup)

3.  Delete the key.

4.  Close the Registry Editor.

5.  Open the Command Prompt (Start > Run > CMD)

6.  Type the following command:
[Path to Setup.exe]\setup.exe /action=install /INSTALLSHAREDDIR=”C:\Program Files\Microsoft SQL Server\" /INSTALLSHAREDWOWDIR=”C:\Program Files (x86)\Microsoft SQL Server\" (MSDN, 2011)

7.  Press Enter.  The SQL Server Setup launches from the beginning.


"INSTALLSHAREDDIR" is the 64-bit shared component files directory with a path of "Program Files\Microsoft SQL Server" (Microsoft Support, 2011)

"INSTALLSHAREDWOWDIR" is the 32-bit shared component files with a path of "Program Files(x86)\Microsoft SQL Server" (Microsoft Support, 2011)

When specifying the the directories, there are known issues with putting a "\" at the end of the path.  For this reason, omit the symbol.

Good - Program Files\Microsoft SQL Server
Bad - Program Files\Microsoft SQL Server\
