Lotus Notes Interop.Domino.dll for 64 bit OS

I have created a simple application of reading mail properties from a nsf file using Interop.Domino.dll, things works fine for 32 bit OS but when i attempt to run the same application under 64 bit OS i am unable to create LotusNotes Session , getting the COM Exception. Though i can run the same application on 64 bit by changing the plaform to "x86" but if i change the platform to "Any CPU" it开发者_开发问答s not working.

I have few other dlls which are meanted for 64 bit machine so i need to keep the Platform to "Any CPU", but in this scenerio i am unable to register the Interop.Domino.dll

Is there any Solution to it.

Thanks and Regards, Haseena

The Domino server api is available in x86 and x64 flavors, so you would need to build against the appropriate one. The client api is x86 only, and if you are linking to that, it would behave the way you describe.
