CPngImage class in oldest version of MFC is not present

[majklha]

I had developed some part of code in MFC with actual version of MFC (WINVER 0x0A00), witch used CPngImage. When I copied it to my application project, developed in older version of MFC (WINVER 0x0600) the class CPngImage was not present. I tried to change the version of WINVER to newer (0x0A00). The class CPngImage was found, but the many of other errors appeared. Very strange errors - see picture below.

What I should to do with it?
