I downloaded and installed yesterday with no issues. I even used GE 7.27
It had the option to install to the computer 1st, which surprised me when it actually worked...

I've not tried the openmapchest source, however I have found 1 issue with the openstreetmaps here in the states, they don't have a good address database for searching/routing.

Other than that, the maps are more up ...
