Duplicate Detection Always Finding 0 Records
If you encounter a situation where your duplicate detection always finds no duplicates, and the fields are assigned properly, it's likely one of two things:1) The formatdups files have become corrupted. These files are saved in the C:\Program Files\AccuZIP6 5.0\Support folder, and will need to be recreated. To do so, download and extract the contents of the zip file linked below to that location, overwriting the previous files.

2) If saving those files has no impact, make sure you have a default printer driver selected that's capable of printing a standard letter-sized report. The Duplicate Detection buffers the report at the same time, so if you don't have a default driver, it will always show 0 dupes selected.
