__int64' followed by 'int64' is illegal

i have very old project who has been made in visual studio 2008 with windows xp 32 bit. I am trying to run this project in windows 7 64 bit with visual studio 2017.

i dont know much details about the project. i know that MFC MBCS pakage was use.

so now i am trying to compile it and got some compilation errors. the main one is :

__int64' followed by 'int64' is illegal in the stdint.h file. the line that get the error is:

#define long long int64_d

i check the project and there is no call or use of the stdint header.

i read that it can be because the code build with C99 and now i try to compile with higher version then c++11.

any help will be very appraised.

Thank You!
