Activation issues with Windows 8.1 x64
first off, the title of your post should read, activation issues with Windows Blinds 8, and not Windows 8.1 x64, even though that is the OS you are using.
1st. did you uninstall the demo, and restart the computer.
2nd did you download the full version window blinds 8.03 from the Stardock store account you purchased the software under?
3rd did you disable your antivirus/firewall before installing the new software.
4th activate with your email address and Stardock password, not the serial number, as it works much better.
5th restart system after install and activation are complete.
you should not have to run the software as administrator because that can cause issues with the install and running of the software properly.
please verify these steps and retry the software.
cheers
