These maps are now in the atlas. Great work. Thanks for the contribution @Don Anderson Jr.

No, CA3 doesn't really care about the location, it just lives in the CC3+ folders wherever they might be.

Did you get the right version of the CA3 installer? There is one installer for CC3 and one for CC3+.

CC3+ always does a split install. The actual program itself is always installed to the C-drive, but it is extremely tiny (less than 100MB with absolutely everything installed), the rest goes to the location you chose for your data directory in the CC3+ installer (Which I presume is e:\ something in your case), which is the bulk of the install (art, configuration, templates, maps, drawing tools, symbol catalogs, and all the rest)

Any add-ons installed after that will never ask for location, but just go to the appropriate directory of the two. Components needed by the program itself (mostly things like .dll files) will be added to the folder on C, but any content will be added to the data directory in your chosen location.

I don't remember the screens in the installer for the Annual 2023 off the top of my head, but at least some of our products have a screen with a checkbox that enable you to do an "artwork only" install (for use without CC3+). I don't remember if the 2023 annual had this, but if it does, make sure to NOT enable that option during install, or it will only install the artwork for use with other software, and not the CC3+ components. Try rerunning the installer and see if this is the case.

If links are obvious (like a city map linking to the labeled city marker on an overland map), you don't really need to do anything. If it is harder to understand without a explanation, either just explain it to me in writing, or put a rectangle or something (with optional text) on a dedicated layer which I can just hide or delete when I am done with it. Just name the layer something that make it obvious that it is a temporary layer and don't conflict with the MAP LINKS layer I use.
