Yes, This is coming from the deployment scanner and is likely not relevant to you because you are not going to be doing Notes archiving. Deselect, ignore.
I would suggest that if you are installing an older version (14.2 is the new hottness IIRC) and tripping up currently you may be in for an uphill battle. I too am a guy who does not read the IKEA instructions but this one may save you a few hours to take a review.
If you don't have Lotus Notes server:
Check if the following key is set to "Not Installed"
