SDK C# Examples on Vista 64

[JaredFleming]

I've attempted to run the OptiTrack c# Multi-camera example on Vista64, but the application generates an error. In addition, I wrote my own C# application that uses the optitrack.dll. That application crashes as well. From my initial testing it appears that Vista 64 throws an exception as soon as my code hits anything to do with the optitrack.dll.

Does anyone have any insight for me?

Couple Points of Clarification:

1) The samples and my application work fine on Windows XP.
2) All code is compiled with Visual Studio 2005.
3) The Vista64 error generated is not useful. It just tells me the application had to close.

I found the problem. For 64-bit platforms (XP64 and Vista64) when you use 3rd party COM DLLs you sometimes need to set your "Platform Target" to "X86". Visual Studio defaults to "Any CPU". It may be useful for NaturalPoint to update their sample projects to reflect this need.

Just another note. The problem seems to still occur on XP64. Vista64 works fine.

Thats great but could you go into a little more detail on how you do this please?

Thanks, JHF, I had the same problem, but with your solution, it works. ProjectPolitoy, you have to click on the "Any CPU" combo in the visual studio interface, then go to configuration manager and add the x86 configuration. Then you compile with that and it works. I am working with a Windows 7 x64, but the sample code only works with the x86 configuration.
