I am having a problem using Wolfram .NET/Link on a 64-bit Windows Server 2008 system. I have an "AnyCPU" .NET program that uses .NET/ Link to start up and interface with the Math Kernel. It looks like .NET/Link itself is working, but it is failing to start up a kernel. Here is the exception: System.Exception: System.TypeInitializationException: The type initializer for 'Wolfram.NETLink.Internal.NativeLink' threw an exception. ---> System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at Wolfram.NETLink.Internal.WindowsMathLinkAPIProvider.MLBegin(IntPtr zero) at Wolfram.NETLink.Internal.NativeLink..cctor() --- End of inner exception stack trace --- at Wolfram.NETLink.Internal.NativeLink..ctor(String cmdLine) at Wolfram.NETLink.MathKernel.Connect() at Wolfram.NETLink.MathKernel.Compute() at XXX.ExecuteCommand(InputValue ivValue, Int32 iKernelToUse) at XXX.MathematicaSyntaxCheck(String strExpression) at XXX.InvokeMethod(String methodName, String xmlMessage, Byte objBytes) We are running Mathematica 6.0, and I did notice that Mathematica is installed in the "Program Files (x86)" folder. My assumption is that .NET/Link is running in 64-bit mode and attempting to start a 32- bit Kernel. Is there something I need to ask my IT department to change to get this working properly?
