A small percentage of my users were getting this error even though most users could install it on the same device, and I was banging my head against the wall to try to figure out why.
Turns out that this error sometimes means that the app isn't available in the user's country! Most of the time country incompatibility gives my users an error along the lines of "this app is not available in your country," but apparently under some circumstances it just gives you a generic "devices incompatible" message. So if you can't make it work with the above answers, find out the user's country and add it to your distribution list.
