SQL Server installation x64 on 64 bit windows

While doing the installation of SQL Server 2008 on windows server 2008 64 bit version, if you try to change the installation path of the sql server... you get an error message as:

Error on install : The INSTANCESHAREDWOWDIR command line value was not specified.

IN order to resolve this issue you can perform the following steps so as to overcome the installation error while installing the server on another drive.....

1.       Run the setup, select all the features you want to install. DO NOT change the install folder, press next

2.       When you see the screen displaying the configuration summary, check the config.ini path, then copy/paste the file on another drive/folder

3.       Edit this file to set correct values for INSTALLSHAREDDIR & INSTALLSHAREDWOWDIR (for my case I set D:\Microsoft Sql Server and D:\Microsoft Sql Server (x86)).

4.       Run setup from the command line : setup.exe /q /action=Install /configurationfile=

This is all you need to do n enjoy working on SQL Server 2008 with a much higher performance as compared to 32 version windows.
