I have PSE 2021, Editor version 19.0 (20210304.m.156367) x64, Organiser version
19.0 (20210126.m.155261). No updates available for either as Update button greyed out. I also have DNG converter 184.108.40.2068 (the latest I think).
PSE camera raw is version 13.0 and there seems no way to update it to version 13.2 which should support RAW files from my alpha 1. I have tried the DNG converter on both my desktop and laptop computers and it cannot see any RAW files, even if I change the preferences to compatability with camera raw 13.2 and later. When I change this to 13.2 it reverts to 12.4 when I close and reopen DNG converter.
As far as I can see I will have to wait until PSE 2022 is released, or buy Photoshop which contains much more functionality than I am ever going to use.
