Duplicate Annihilator - 2.23.3

This looks interesting, but notes don't mention iPhoto '09—has it been tested yet?

I merged iPhoto libraries from three computers and then set out to remove duplicates for the resulting 16,000 plus files. Read about Duplicate Annihilator, saw the great price, and decided to try. It does annihilate some duplicates, but at a Chinese water torture-like pace. Seriously, it was evaluating about 985 files per hour, so in my case over 16 hrs of crunching. By the time you figure out the pace, you already have a significant time commitment. It did identify 3000+ duplicates, which I successfully trashed. When going back to the library, it was obvious that there were still many many more duplicates remaining. I'm not sure how the software works, but I suspect that "duplicate" as opposed to "replicate" may be key problem. Also not sure how it handles an original vs 90° rotated file. I'm on my second cycle of reprocessing now - should just be another 12 hours or so. This might be just the thing if you have a spare computer and week or so to crunch while unattended (although it may detract from SETI). However, one can eliminate "replicates" far faster by manual visual inspection in iPhoto (using sort options) - even with 16,000 photos. The documentation doesn't warn that this will be a slow process. I guess I'm still looking for "Warp-drive Replicate Annihilator".

This is not the correct download file format. It works however from the developer's page.

I downloaded the latest update. It turned my REGISTERED version into a DEMO!!!
Good going guys! Geez.
