OpenCV Visual Studio ntdll.dll

Question

I have trying to create a Project using OpenCV 2.4.10 on Visual Studio 2013, but I have had very little luck so far, owing to the following exceptions. Please suggest help. TIA.

'letstryitonemoretime.exe' (Win32): Loaded 'C:\Users\Kndarp\Documents\Visual Studio 2013\Projects\letstryitonemoretime\Debug\letstryitonemoretime.exe'. Symbols loaded.

Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x.

I got the same error message because my program was trying to load a 32-bit DLL instead of the 64-bit DLL. You can see which DLLs your program is trying to load using Dependency Walker .

Do the following steps:

1. Open Dependency Walker
2. Open your executable (File->Open select your executable)
3. Make sure all your DLLs use the same CPU architecture. The middle pane lists all the DLL your program is using. The CPU column says if the DLL is 32-bit or 64-bit. They should all be the same.

In my case one of the DLLS was 32-bit instead of 64-bit because I had not added the 64-bit DLL to my environment path. I just copied the 64-bit DLL into the same folder as my program binary and the error went away.
