The short version: I have two "MapSource" apps -- a "Roads and Recreation" version (executable version 2.01 -- 1 CD of data) and a "Topo" version (executable version 3.02 -- 3 CDs of data). I cannot seem to get these apps to co-exist. When I install both, the first-installed version subsequently, when run, craps out with an error dialog that tells me to call Garmin. Worthless. It appears that these are out of synch with each other (big surprise!), and they both share the same Registry entry, thus clobbering each other. What great software!
Do you have these apps yourself? If so, have you been able to get them to both work concurrently? If so, what the *^%$@*! do I need to do to get them both working? I'm running a Dell XPS R450 -- a Pentium II tower, 450 MHz, 256MB RAM and Windoze NT4 SP6a.
