cannot download maps in my downloads into garmin basecamp

[watermelon439]

I have windows 8.1 I can download maps from gpsfiledepot into my downloads and documents, but when I go to basecamp, i cannot pull them up and download them into basecamp.

Maps must be properly installed on your computer before you open Basecamp. Almost all maps here include an installer program (.exe file). Run the installer and follow the instructions.

Now open Basecamp and you should see the map on the menu.

I just purchased a new ASUS labtop with Win 11 and can't get any WI or MN Topo maps you have to work with Garmin Basecamp. They down load fine but Basecamp will not open any folders or maps. I have a Dell with Win 10 and used your maps for many years. Any ideas? THANKS
