Problem with open cv

[Elnaz]

Well, I'm trying to use open cv in VS 2010 on Windows 7 64 bit. I've added all the dll and lib files and included the path in system variables but when I hit debug I get this error message that: The application was unable to start correctly (0xc000003b). And when I hit start without debugging I get: The application can't start because cxcore210d.dll is missing from your computer.
The dll file is in the bin folder of opencv 2.1 and I even have included it in Windows/system 32 folder but still nothing!
Does anybody know the solution here?
Thanks
Elnaz

Previously, I had installed the prebuilt version of opencv. This time I used CMake and did everything as it was instructed. However, when I try to run the "hello_world" example I get : The application was unable to start correctly (oxc000003b).
Does anybody know what is going on here? What can I do next?

Were the prebuilt .dlls working for you? Did CMake report any errors? Have you re-compiled the hello-world example since making the new .dlls? (I can't imagine that should make a difference, but.)
