WINDOWS PROTECTED YOUR PC 

This one is a nice easy one and means Windows Defender is doing its job by alerting that you are attempting to download from the internet rather than the store. 

1. You will notice in the alert text that the words MORE INFO are underlined; click to reveal further text. 
2. An option to RUN ANYWAY will now appear at the moment; select to continue the download process

3. Once downloading is complete, ensure to right-click on the vanspace 3D icon that is installed on your desktop, and select RUN AS ADMINISTRATOR
