Hey @KHIMOD! Welcome to the forums!
You may need to just give it time. In the 62-85% range, depending on version, it tends to hang as it is installing some large files, and bases progress on number of files installed, not size. Try giving it a little more time! When I see this the solution is almost always a matter of waiting. 
And if it doesn’t move after 30 minutes, restart the installation.
