'atlbase.h': No such file or directory

Error code:
#include <atlbase.h>

1    error C1083: Cannot open include file: 'atlbase.h': No such file or directory
2    IntelliSense: cannot open source file "atlbase.h"

This error occurs if you are using atlbase.h file in your program in Visual C++ Express Edition instead of Visual Studio. The reason is express edition does not come with Microsoft Platform SDK as studio does so we need to install it separately and need to modify a couple of lines.

1. Download and install Windows Server 2003 SP1 Platform SDK from
2. If you have a 64-bit OS/Processor (Intel i5, Windows 7 64-bit) then install PSDK-amd64.exe as other two won't work.
3. Go to your installation directory to edit atlbase.h file, default would be C:\Program Files\Microsoft Platform SDK\Include\atl
4. Make following changes
