I installed the new BaseCamp on my notebook. But when I ran it, it no longer sees my 100k Topo maps. I checked the Windows Registry and I see there is a folder called Installed which has all my maps except 100k Topos. I see that under Mapsource there is a folder called Products that does have them. My theory is that the new Basecamp no longer searces the Mapsource folders for installed products. So maybe I could create entries in the Installed folder for the 100k Topos. But I don't know how or really what to do. Any advice or opinions?
