Run Internet Information Services (IIS) in 32 bit emulation mode

Posted in Sharepoint, Windows by Abhishek Bhowmick on September 30, 2008

If you are running Windows Server 2003 x64 based operating system and you are installing x86 based application which would need to run on Internet Information Services (IIS) then you must run IIS in 32 bit emulation mode.  To do this follow the steps below:

• Click Start, and then click Run.
• In the Open box, type cmd, and then click OK.
• In the command prompt window, navigate to the %drive%:\Inetpub\Adminscripts folder, where %drive% is the drive in which Windows Server 2003 is installed.
• In the Adminscripts folder, type the following command:
cscript adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1

Note: The value “1” for Enable32bitAppOnWin64 specifies 32-bit mode, whereas the value “0” specifies 64-bit mode.

• Press ENTER.
• Type iisreset and then press ENTER.
• Close the command prompt window.

IIS would now run in 32 bit emulation mode and you can now install x86 based applications on the server.
