Sharepoint install: 32 bit emulation mode in IIS

September 24, 2008 – 17:51 by Tom Van den Berg

If you are running the Microsoft Sharepoint Services installer on a x64 machine with Microsoft Windows 64 bit installed and you get an error like this:

IIS is running in 32-bit emulation mode, please fix this error to continue’.

You must run the following script from the command line:

CScript "%SystemDrive%\InetPub\AdminScripts\adsutil.vbs" set w3svc/AppPools/Enable32bitAppOnWin64 0

and do an IISRESET

Start the installer again…

  2. Actually, you want to disable IIS compatability mode to get SharePoint to install on x64 with an x^$ installer copy (preferably slipstreamed with Cumulative Updates and Service Packs.

    So it should be a 0 (not 1) for the argument passed.
