If you wish to run a 32-bit web application under a Windows x64 VPS then you must switch IIS to run in 32-bit mode.

IIS 6.0 is able to run 32-bit Web applications on 64-bit Windows using the Windows-32-on-Windows-64 (WOW64) compatibility layer.

Open a command prompt and navigate to the %systemdrive%\Inetpub\AdminScripts directory.

Type the following command:

cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 "true"
