An MFC application which is connecting oracle db through occi. but it is giving error 0xC000007b on running in 64 bit machine?

Question

I have compiled this application in VS 2010 in 32 bit Win7 and it is working fine on 32 bit machine but giving error "the application is Unable to start correctly 0xc000007b" on 64 bit machine.

After Google it I have checked with Dependency Walker it is giving the error in ORAOCCI11.dll. but don't get any solution to resolve it.

Thanks in advance.

Answer 1

I got the answer of this question by my own so i am answering it. I should use all the 32 bit libraries even on 64 bit system if my all other code is complied in 32 bit so ODAC client should be of also 32 bit.
