Gemini Duplicate Finder with Aperture uninstalled

Running Gemini to remove duplicate photos fails with files listed in Aperture Library. Yosemite Aperture has been uninstalled.

Gemini returns 'cannot delete' because photo is needed to maintain Aperture Library.

How do I disconnect photos from Aperture Library so they can be deleted?  

Maybe just move from current [Library] location? Or will this create other issues re: deletion.

You should do your deletions from within Aperture to avoid screwing up the Aperture database.

As Aperture is no longer installed (I am using Lightroom 5), I no longer have access to the Aperture Database.

I don't think I care about the Aperture Database any longer; I want to delete duplicate photos and rebuild Lightroom catalog.

Essentially I want to start over with set(s) of unduplicated photos used to build Lighroom catalog.
Were the photos stored by Aperture as referenced masters, or as managed images? See:

From the sounds of your description, they were stored as managed images, which means that they are stored in inside the Aperture Library file, rather than being stored in the a folder in the finder. Is that the case?

If it is, the proper procedure would have been to move them out of the Aperture Library into a finder folder following the procedure here:

You best solution at this point, might be to re-install Aperture, re-associate it with the library file, then do the export to the Finder as above.

I would make a backup of the Aperture Library first, just to be on the safe side.
But read this article first on another way to move your photos from Aperture to Lightroom which is probably better:
