Where or what do I add this file to. When I run the mapsource installer I get the post 1 error but there is no folder to drop this into.
I must read, read and read again, the instructions say make the folder on C: and put this in it then put the mapsource .exe file in there also and run it. Then do the same with the patch file. It works of course. If only I could do what I was told the 1st time life would be so much easier. Hope my incompetence helps someone else to get it right first time trying.
