Greetings everyone, I’ve noticed many having difficulties with installing Mercury MSN app so I think the easiest way to do so is:
Download any QR Code scanner from the Play Store (Or your phone might include one already)
then scan this with your phone
it should take you to the download link directly 
Very good idea 
very good Bill 
just one thing. for people who run a simulator probably can’t scan the QR code which is fine because they won’t be able to take the app with them when they leave the house / apartment / flat anyway. the app will just have to be downloaded by going into the mobile browser in the android os and click on the apk download link. that’s the way I did it with android os in my simulator.
