First of all we recommend that you pause your Antivirus software just for the installation and first start of our app.
After downloading our Windows app, double click on it:
When you see the following screen (Windows protected your PC), click on "More info":
Once you clicked on "More Info" you will see a new button at the bottom, "Run anyway". Click that button to install our app (pause your Antivirus app):
Once the app is installed our Windows app will open automatically. Most likely it's downloading the newest update immediately, so give it some 30 seconds to do that. Then you can unpause your Antivirus app.
Login with your usual email and password you used for our website. You will be prompted to also enter your 23andMe email and password (as those are now kept on your computer).
In case your Windows Defender blocks internet access when you're on a public wifi (eg. Starbucks) please do follow these instructions: https://www.youtube.com/watch?v=eRdYYqLnjLk
