When installing on a 64-bit Windows Server, if IIS is not configured to run in 32-bit mode the installer will display the following error in a dialog box:

cscript.exe %SYSTEMDRIVE%\Inetpub\AdminScripts\adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 1
%WINDIR%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe –i –enable

For Windows 2008 running IIS 7.0, follow these steps:
1. Open 'Internet Information Services (IIS) Manager' snapin under Administrative tools.
2. Expand the server and click on 'Application Pools' to display available applicaiton pools in center panel.
3. Right-click on 'DefaultAppPool' and select 'Advanced Settings'.
4. Change the value of 'Enable 32-bit Applications' from False to True. Click OK.
5. In the Actions panel on the right side, click "Set applicaton pool defaults" and do as in step 4 again.
6. Restart IIS service by highlighting IIS server name in left panel and clicking Restart under Actions panel.
