Can't install extensions in Opera 46.0

  • I have a fresh installation of Opera 46.0 on a computer which has never had any previous version of Opera installed. However, when trying to add extensions I receive the following error message:

    An error occurred when installing the extension: Installation failed

  • Further information:

    This only occurs on 64-bit Windows 10, not Windows 7, 64- or 32-bit, suggesting that Opera 46.0 is not 100% compatible with Windows 10 64-bit.

  • suggesting that Opera 46.0 is not 100% compatible with Windows 10 64-bit.

    Or maybe there's something wrong with your installation. 🙂

    Does it happens with any extension?

  • I have Windows 7 32 bit and I can't install extensions either. I could at first but now I can't for some reason. I also can't install themes.

  • Could you do following:

    • go to page with failing extension installation
    • right click on 'Add to Opera' button
    • from context menu choose 'Save linked content as'
    • after .nex file is downloaded drag and drop it onto Opera

    This should probably also fail but hopefully there should appear some toolbar with detailed informations

  • No problems with Windows 7 64 bit.

  • Where do I find the extension folder. There is nothing to click in settings to view, edit, delete, add extensions.. So I am wondering is it a file hidden in the Opera exe folder?

  • Where do I find the extension folder.

    In Opera's profile folder. See Menu > About Opera for the path.
