The error message that you are receiving there indicates that Solidworks has detected your system as being "32-bit Windows 8 OS" and not "Windows 10 Pro".
Are you 100% sure that your computer is 64-bit? Because it certainly doesn't appear so......
Open your control panel, click on system, and view your system details to make sure
As stated earlier in this post (https://forum.solidworks.com/message/712142#comment-712142 ), you need to have 64 bit of OS and not 32 bit.
From where did you bought the SOLIDWORKS? I doubt that you have not bought a legitimate license else your VAR would have told you about the system requirements already.
