Error in AES Encryption using C++

I have done Encryption of a File using C++ with ENCRYPT_ALGORITHM as CALG_RC4. The code is working fine. When I changed the ENCRYPT_ALGORITHM to CALG_AES_256 it fails.

if(CryptAcquireContext(
    &hCryptProv, 
    NULL, 
    MS_ENHANCED_PROV, 
    PROV_RSA_FULL, 
    CRYPT_VERIFYCONTEXT))

and

   if(!CryptDeriveKey(
          hCryptProv, 
          ENCRYPT_ALGORITHM, 
          hHash, 
          KEYLENGTH, 
          &hKey))

fails with the error no. 0x80090016 and 0x8009000f

I want to perform AES 256 Encryption and also want to include the SHA-512 hashing along with the encryption CALG_SHA_512. What are the things I need to modify?

Note: I don't want to use any 3rd Party API's for performing this operation.
