For those who are trying to change GTA5.EXE icon, or edit information inside of it with an EXE editor, I'm telling you that is not possible because:
- The GTA5.EXE original file is encrypted.
- You can actually change icon and some information inside with Resource Hacker (it's the only one that works),
but when you save it and you try to execute it, it won't start because it "detects" changes and it just won't start,
even if you bypass the launcher with any tool.
If you use Rockstar Launcher, it will say that it's outdated and it will download the original version.
