I am signed in to MyWayfinder when I do this. There is a link to the right which says "Install or update your Wayfinder here!" After clicking that I get to a screen where I can choose to install either Wayfinder 6 or 7. The link to install 7 is here Wayfinder - your navigation homepage

I am having trouble with the link as it appears the link may be dead at the moment. It states you can try to get it via SMS, but I have not gotten replies to my 3 texts to them. It also states you can download from getwf.com, but that link only takes me directly to version 6.
