XnView Software

I just downloaded XnViewMP 1.4.3 on macOS Monterey 12.6.3 and when running for the first time I get this: (I said no to keeping thumbnails):
XnViewMP - There is a problem to update catalog (Error: 13), please contact the developer

it seems that you had a very old version, you need to remove .xnviewmp/XnView.db

A million thanks. That solved it!
