It didn't work for me, at first. To help any others out there, if you insist on entering the key manually, don't put the quotes in. At least, that's what worked for me. However, if you are at all unsure of what you are doing, wait until the automatic update is there. Hopefully, Codetwister will have a way of determining where the Poser.exe file is, as it could well be different for you than it is for me. One way might be to have The Tailor program look at the HKEY_CLASSES_ROOTpz3fileDefaultIcon entry in the registry, as it is the same as the entry that I put in. Although it uses .cr2 files and not .pz3 files, the path is the same. Just a suggestion.
