i have the same os as you and i have to say non of the hacks using fin work for me either i use valk and perx you should too if you want links i can give u.
Do this.
1. Right click faith injector.
2. Go "Troubleshoot Compatibility"
3. Let it scan. And choose the recomended settings.
4. It'll ask you to open faith to make sure it works. Open faith, It should auto run as admin now but if it doesn't run as admin.
5. Press Ok in the troubleshooting window & Choose to keep theese settings.
Also make sure you have netframeworks installed.
Then try running the normal process of Injecting and oepning crossfire. This fixed my problem and I just use the Basic Crossfire Hack with no hotkeys and just boxes and no sky. Hope this helped.
