Error 7203 when running .NET Open Client on 64-bit environment

Error 7203 when running .NET Open Client on 64-bit environment
 

Calling the .NET proxy from a .NET application
Using .NET 2.0 Framework

The .NET application has been compiled with the 'Any CPU' Compiler option. It needs to be compiled with the 32-bit compiler option.

Part of the .NET Open Client runtime libraries are 32 bit native code in OpenEdge 10.x and cannot be run as a 64-bit application.

For ASP.NET 2.0, run as a 32-bit application instead of 64-bit.

For further information about how to switch to 32-bit version of ASP.NET, check http://support.microsoft.com/kb/894435

For a Windows Forms .NET application, set the /platform:x86 option for the compiler in the .NET project instead of 'Any CPU'.

For further information about how to set this compiler option in the Visual Studio environment, check the following MSDN article:
