Painter Essentials 7 Installation Trouble

Hello, I purchased a Wacom tablet with the software download of Painter Essentials 7 and have gotten past the first phase of downloading, an icon has appeared on the desktop which says 'continue painter essentials 7 installation' but when I click this a progress bar appears and sometimes freezes partway through, sometimes disappears at 0%, and sometimes makes it all the way to 100% before disappearing but then nothing happens and it isn't installed. I don't know what to do and would appreciate any advice please as it's quite frustrating! I'm on a Lenovo Yoga 300 laptop, and running Windows 8, I have tried disabling firewall, running as administrator, everything else I could think of but no luck! Thank you in advance!
