Did you reboot after the install? Did you have anything else running during the install? That can definitely cause problems.
Are your system specs correct? Sometimes on Win 7/8, you need to install using elevated privileges ("Run as Administrator"). I wouldn't think that would be true of Win10, but it wouldn't hurt to reboot your system (Make sure nothing else is running. Disable your antivirus just in case), and try a new install, with Run as Admin.
Afterwards, reboot your system again, and don't forget to re-enable the antivirus (though the reboot normally does that).
