The link to the site on the cover is invalid. Then I look for another similar website published by this company and follow their instructions according to the video which resulted in the screen protector ripping. This company is very nice and sent me a new replacement and I was able to install it correctly. For a successful installation of this product, we need to take care of two things: 1. NEVER fold the film.2. Thoroughly clean your laptop's touchscreen. Start at the top (with 4 holes), line it up correctly. After leveling, simply remove the glass, it will laminate itself.
