If you have a question, please read the linked article first as it may answer it. It is a complete and detailed writeup which can be found here:
You will do the described steps at your own risk. I am not to be held accountable for any damage you cause to your system. And if you are following this guide correctly, there is no way any damage can occur. I do not endorse hacking applications but since the check that prevents installing Pro Tools 10 on newer systems is mostly arbitrary and the program costs a lot of money the steps described are reasonable.
Following a guide from start to finish before executing the commands is always a good idea and also: even if you can now successfully install Pro Tools 10 on your system, it is still not supported by Avid and may crash regularly, have other bugs or not run at all.
