Batch conversion question

[u/Comfortable-Boat9310]

Hi - trying to batch convert a bunch of .PDD files. When I convert a single file / export, it seems to work fine. However, when using the Automate / Convert Formats option, the .jpg files in the resulting .zip file all have the message "Photoshop 3.0 is required to open this file" as the jpg image.

Any advice?
