Hi,
Greetings!
I have a question on MFC (Microsoft Foundation Class) currently I am reverse engineering the C++ code which was developed in 1998. The code is incorporated with 4.21 version of MFC Library.
Now we have built the code in Microsoft Visual Studio 2019 Professional Edition (Version: 16.11.22).
Right now the Executable is Crashing when we try to access some functions, it says MFC version should not be Newer than 4.21.
Please help me how to make MFC Library to support for the current version.
Thank you,
Hanumesh

You'll need to supply more details.
I suspect you might have a DLL build with the older version that you've not rebuilt with the newer tools - but I'm only guessing.
Hi David,
Yes the code i have now is built with older version of DLL.
Now i am trying to rebuild and incorporate with current version of DLL.
Yes, rebuild all your component DLLs that depend on MFC with the same version of the tools. Hopefully that'll solve your issue.
Now I have rebuilt my code and generated the executable, the problem is it is Decades old code and it has 4.21 Version of MFC Library, in Visual Studio 2019 version 4.21 MFC Library is not available.
Please suggest how to cater 4.21 version of MFC to make it to work.
Maybe the old code can be compiled using the current version of MFC. Did you receive some compilation errors?
Thanks much David :)

Did David's comment solve your problem?
