Hi Guys:
Yea, I have been through all that stuff myself - no fun.
Here are some tips, based on my experience:
1) The most recent cartography products (CN and CS Europe version 5 and 6) follow Microsoft's conventions concerning installer behaviour, and thus make an entry on the "Add-Remove Programs" list, which you can access through the Windows Control Panel. This means if you are upgrading from version 5 to version 6, do the upgrade and full install of 6 first, unlock it, make sure it works, then go to the Windows control panel, Add/Remove programs applet, and remove the previous version (version 5). Don't, however, delete early versions of the product which are not listed by version number in the Add/Remove Programs list (e.g. version 4) if those early versions were your first "full" purchase (meaning, if you bought the GPSR with version 4, then bought an upgrade to 5, and then bought another upgrade to 6).
If you have bought a new GPSR (e.g. a SP 26xx) and it came with version 6 in the box, then delete everything from your computer first if you wish, and do a fresh install of the version 6 cartography. Because the new cartography will have a "full" unlock (meaning, it's not an upgrade package), it does not look for the presence of any previous version installs.
2) I have no idea what causes the computer to sometimes get into that funny behaviour of asking for a CD that is already in it. But, I do know that if you completly ignore the dialog about the CD that has "abort, retry, ignore" as the choices, and just finish up the work as if it was not there, then the install completes just fine. Note that if you want to ignore this dialog, you have to give focus to (click on) the window you want to work with, which is, presumably, the MapSource installer window.
Be aware that you can get two different types of requests for CD changes - one from the MapSource application (this will specify the name of the CD, e.g. 'Insert City Navigator CD 2'), and one from the OS itself (the abort, retry, ignore one). The one you want to totally ignore (don't even click on one of the choices) is the notification from the OS.
Alan: Honestly, my heart bleeds asparagus juice for you - all that trouble with computers. Good on you to get rid of the whole lot of them and go back to paper maps and a #2 HB pencil.
If you had read and followed the directions for the upgrade, you would not have had any problems. You didn't follow the directions, you deleted your previous version first. This is not a smart thing to do with any upgrade, including software upgrades for the Mac OS. Normally, software upgrade packages (any OS - Wintel, OS2, Mac, Unix) look to make sure a previous version has been installed first, I think you should know that.
Finally - what the heck are you doing loading version 5? Isn't the current version 6?
