Hi, the topic I linked you to has a download which registers all of the required files for you. It looks like you tried doing it manually which is more complicated. I've already told you via PM this.
Run the installer and then restart your computer. Make sure you do not have an antivirus blocking the program.
And make sure you are running as Admin.
Edit: I moved your topic somewhere more appropriate. Please read our posts here as people have had this same issue and managed to solve it.
