But first you can try going to internet explorer==tools--internet options and there go to security and privacy and in those 2 options you will find you can disable popup blocker, accept alll cookies, turn security level to low or zero and press apply==ok to lower all security which stops the download.

Having done that, when you click the download button keep the Ctrl key pressed down

Thats the 1st thing to try

If that does not work, May be you have a firewall blocking, you may need to disable windows
firewall, or the existing anti-virus's firewall

Try uninstalling or disabling existing anti virus software
then try to download keeping Ctrl key pressed as you click the download button

If that does not work-it probably will-

Go to "contact us" on the page where you downloaded after purchase, and send message stating
your payment transaction ID, product key, and the exact error you are getting, they will repair it. They do store your product key online, ask them

I hope that was of some help. Get back to me if you have any more questions
