Program not working after Retargeting

Okay so basically I was using VS 2015 and windows 7 before, I changed to windows 8.1 and VS 2017 and when I tried working on this project I started having problems. Everything was having errors, to do with other libraries not being found (like a few hundred errorS) VS prompted me to re-target the solution and when I did that it didn’t give any errors, but now when I run/compile my code it doesn’t show anything besides “Press any key to continue” but all my code is there in the C++ file.
