This object always uses the default value on the system, so on the x64 machine it will use the x64 Internet Explorer object. Is there a way to get it to use IE x86? The webpage element accessed by the browser does not work on x64 and is out of my control.
You can force the forms application to compile in x86 on the Visual Studio project property pages. Properties -> Build -> Platform Target
Properties -> Build -> Platform Target
Compile your program in X86 mode.
