I must admit, I seldom use those plug-ins myself. I don't seem to have a problem with the new version. Some of them are still 16-bits and working. I have both the 32-bits and the 64-bits of PSP 2022 (and older versions) installed as I get questions on a daily basis about the old plug-ins. My pc has had the Windows check and it is ready for Windows 11. Personally I prefer to remove any obstacles that could cause future compatibility issues with Windows 11. Keep in mind, the writing is on the wall, 32 bit processing is being phased out. I would recommend against installing the 32 bit portion as it will most likely reduce efficiency in processing, but if you have older add-ons they may not work without installing both 32 bit and 64 bit versions. Windows 11 is just around the corner and it is focused on 64 bit archetecture. First impression is that it seems to open faster but that is yet to be seen.
