Problem with shell extension after 17.6 update


After installing 17.6 (4.10.2187.0/SAFE) update from Elisa (Elisa Turvapaketti) this week I started to get strange issues like:

- Directory Opus file manager crashes when double clicking video files, DO resports issue to be in FsShellExtension64.dll

- Start menu (right click) Computer Management and many other tools don't start

Never had these before. And I was able to track the cause to be FsShellExtension64.dll, which I then diabled using ShellExView tool. That solved all those problems. But this is not a long term solution for the issue and I hope F-Secure can fix the isue, which seems to be only in 17.6 update as it did not appear in any older releases.

    Same problem, contex menu in Win 10 crashes win 10. Disabling

    CppShellExtContextMenuHandler.FileContextMenuExt Class of F-Secure Corporation with ShellExView.exe repairs the issue...

    Same problem here. Wasted some hours to figure this out.

    Sorry for my reply. I am only an F-Secure user (their home solutions).


    Based on recent beta (and its release notes), probably, such trouble is fixed for "beta" builds.

    But a bit unclear whether it is about this trouble or not (and when such a fix is rolls out to stable solutions).


    I do able to suggest contact their direct Support Channels (for example, chat):


    To ask them and maybe to receive help.
