An Attempt to Write a Ram Patch Installer

[FantasyAcquiesce]

Hello MSFN,
To challenge myself in coding, I am trying to make a simple C++ based installer for diyba's ram patch. I know there are better out there, but this is mainly for me to apply C++ (I do not know any other coding languages besides a tiny bit of java).

So far, things were going OK, until I changed Visual Studio 2019's tools to a Windows XP-compatible tool. Now, I have a syntax error mentioning something cannot be converted. I am quite confused and am wondering if I should just use another IDE or something.

I am a complete newbie to coding.
