Something not right with ON1 registering as installed app

    This would appear to be a bug in the installers.  Although I have installed at least 3 versions of 2021 , I only show 1 currently installed. I still have 2020 installed, and that shows 2 different versions present in the Apps section of Windows.  These 'extra' versions are merely entries in a list of installed apps, and don't really reflect GBs of lost disk space. Each update version gets written to the same folder as the ".0" version was installed to.

    When these extra entries get left behind may depend on whether the installer is run from within On1 RAW or as a standalone installer, or there could be some other reason for it. 

    Support may have a utility or process to clean those up. There are ways to manually clean those up, but they involve manually editing the Windows registry, and I wouldn't recommend that because it's very easy to make mistakes that lead to big problems.

    I've seen this problem with products from other companies as well.

    Leif, Regarding Raw 2020 being in your list of apps.

    Open Control Panel by typing Control Panel in the search box bottom left side of the Windows Task Bar.

    In Control Panel, Select "Programs" then Select "Programs and Features"

    Right Click on Photo raw 2020 in the list then the click uninstall. If the application cannot be found you should get an option pop up to remove it from the list. ( Not sure why the Windows team decided to leave this option out when they added the Apps list to the Settings panels but they did. )

    You may also see older files directories of 2020 or 2019 etc.. left behind if you used those versions before and uninstalled the program. You can safely delete any folders of those previous versions found in Windows File Explorer  if the program is indeed uninstalled.  As Carl indicates many applications leave orphaned folders and directories behind when they are uninstalled.

    As a side note I do not see the same issue as you with multiple On1 Photo Raw 2021 instances listed.

    One thing to note about deleting folders for older versions in Windows File Explorer is that when the program gets updated or reinstalled or even if the Reset ON1 Photo RAW button is used the folders for the previous major version are used for migration; i.e.; 2021 looks at 2020's folders to do the migration. If you delete the 2020 folders then have to reset or reinstall the program you will have to reimport all Presets, LUTs, and other goodies you've downloaded and installed. You will also loose all Presets you may have made for yourself.

    If that is a concern, keep the 2020 folders but get rid of 2019 and earlier.

    Thanks Brian – but just to clarify, should those folders not only be required when you do the migration to 2021? Once it's done, should you not be able to delete the 2020 folders then? Or, are you saying that you always need to keep the folders for two major versions in parallel, and only delete 2020 once you, say, upgrade from 2021 to 2022?

    Yes, once the migration is done those folders from the previous version won't be needed any more. Unless you have to go back and reinstall or reset the software. Then the program will do the migration again if those folders are still there.

    Personally, I got rid of everything except 2021 folders. You will find though that the 2021 program will create another ON1 Photo RAW 2020 folder for some reason. It is essentially empty though so I don't worry about it coming back.

    OK. I guess my view would be that this whole process of upgrades, installations and uninstallations could be handled better by the ON1 software. In the end, I had to do the following to get rid of the extraneous installation traces that were not possible to uninstall through the normal Windows route:

    1. Go to C:\Program Files\ON1\ON1 Photo RAW 2020
    2. Rename "maintenancetool.exe.new" to "maintenancetool.exe"
    3. Rename "maintenancetool.dat.new" to "maintenancetool.dat"
    4. Run maintenancetool.exe. This removes most of the installed files.
    5. Go to C:\Users\<user name>\AppData and check whether left-over files are in either Local\ON1 or Roaming\ON1 (in my case, I had to delete the whole directory "C:\Users\<user name>\AppData\Roaming\ON1 Photo RAW 2020").

    Hope this helps anyone else with the same problem.
