[Windows] Cura does not remove "open with" options


Recommended Posts

Posted (edited) · [Windows] Cura does not remove "open with" options

Maybe I am missing something but everytime Cura tells me an update is available I download and install the newer version but the Windows "open with" dialog still displays all previous version. Is this a bug in the installer/uninstaller or am I missing something?



Edit: makes sense to supply my windows version too :)

Windows 11 Version 21H2

    I don't think it uninstalls previous versions by default.  I need the older versions but most folks don't.

    If you click on the Start button and scroll down to the Ultimaker section you can right click on a version you no longer want and select "Uninstall".  That should take you to the applications list where you can actually perform the uninstall.

    I don't know if it's a bug or not.

    After I install a new version of Cura I have a second installer (of my own) that copies my custom definitions, scripts, extruders, and nozzles into the appropriate folders of the new version.

    When I uninstall, the uninstaller appears to leave those folders that have my custom files.  I would assume that in my case it's because the files inside those folders aren't listed within the uninstaller and since they remain on the PC the folders they are in remain as well.  I have to manually delete those folders.

    But the "Open With" menu is something different, but may be related.  Maybe @nallath can cast some light on the subject.

    regedit > HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.stl.<cura version number>

    deleting the old versions seems to work for me.


    I noticed windows uses this key if you use the 'open with' > 'choose another app' dialog
