compiler errors in atlconv.h,atliface.h in VC MFC program
===

I have a VC++ MFC COM component developed in VC++6.0 earlier. Now my pc has installed with VS 2005 and VS 2010. 

Now I have a new changes to my old code which i built in VC++6.0, I have opened VC++6.0 and trying to run the application then i am receiving errors in **compiler errors in atlconv.h in VC++ MFC program** atliface.h #define #endif errors etc., 

Is the installation of newer versions corrupted atl files by any chance. How do i overcome these atl errors? please suggest me.

thanks in advance.
