Configure ASP.NET to use x86 on x64 Windows
I am trying to deploy GAL Modifier , which is an ASP.NET website which uses Microsoft Access on a Windows 2003 x64 machine.

However as it is a web site there is no option in Visual Studio except Any CPU, so how can I change the settings to force it to use x86?
