I used to have an excellent product from FSquality which upgraded the road networks in the UK and Western Europe. This does not however work on my new platform with Windows7 64bit OS.
I have looked high and wide for a replacement product which gives good visual roads with detailed intersections etc and makes VFR flights much more realistic, but found nothing.
There is a company called R.Taburet who did lots of road upgrades, plus USA Roads by Scenery Solutions etc, but these were all designed back in 2004/5 and are either no longer available or I have no doubt will also not be compatible with Windows7.
Surely there is something newer and better out there - isn't there?
Is this what you need.
Yes, that's the kind of thing I am looking for, but obviously for FS2004.
Ask here, they should be able to help.
