Delete old version

    Personally, unless you absolutely need to recover the disk space, I would leave all the 2020 stuff in your <user>/AppData/Roaming/ON1 directory there. If you ever have to uninstall then reinstall 2022 it will be needed for the migration process. Without it you loose whatever might have been migrated.

    Here is the procedure I use to completely remove the program from my system. You can modify it with my comments above in mind.


    • Uninstall via the Add/Remove Programs 
    • Remove the C:\Program Files\ON1\ON1 Photo RAW 20xx directory 
    • Remove the directories with "20xx" in their names located in C:\ProgramData\ON1 
    • Remove the directories with "20xx" in their names located in C:\Users\<user>\AppData\Roaming\ON1 
    • Remove this directory C:\Users\<user>\AppData\Roaming\Adobe\Lightroom\Modules\ON1 Photo RAW 20xx.lrplugin 
    • Remove this directory C:\Users\<user>\AppData\Roaming\Adobe\Lightroom\Modules\ON1 Resize 20xx-suite.lrplugin 
    • Remove the 20xx files in this directory C:\Users\<user>\AppData\Roaming\Adobe\Lightroom\External Editor Presets 
    • Remove the 20xx files in this directory C:\Program Files\Common Files\Adobe\Plug-Ins\CC

    Thanks for that. I am not pressed for space and I may take your advice and just leave things alone.  Things are working well .(The absolute enemy of good is better)
