An exception occured due to plugin: DSpellCheck.dll



  • Hello,

    I get the following error using the latest version of Notepad++:

    An exception occured due to plugin: DSpellCheck.dll
    Exception reason: vector<T> too long

    After that the application shuts down. The problem consistently occurs when opening a large file (in my case 430 MB) and scrolling through it by dragging the scroll bar on the right side with the mouse.

    Notepad++ v7.6.3 (64-bit)
    Build time : Jan 27 2019 - 17:16:47
    Path : C:\Program Files\Notepad++\notepad++.exe
    Admin mode : OFF
    Local Conf mode : OFF
    OS : Windows 10 (64-bit)
    Plugins : DSpellCheck.dll mimeTools.dll NppConverter.dll



  • welcome to the notepad++ community, @Werner-Vogelweide

    unfortunately the DSpellCheck plugin still has some issues on files with very long lines without line breaks.

    the only workarounds possible at the moment are these in this order (you can stop at any point, as soon as your issue is resolved):

    • go to plugins > plugins admin and update to DSpellCheck 1.4.9 if you are on a version below that.
      then restart notepad++ and retry with the same documents.

    • go to plugins > DSpellCheck and disable spell check documents automatically
      then restart notepad++ and retry with the same documents.

    • go to plugins > plugins admin and remove DSpellCheck completely as a last resort.

    note: the DSpellCheck plugin will probably not be installed by default any more, when conducting a fresh install of the next version(s), according to the developer, due to the amount of issue reports. it will remain as an optional install at the plugins manager.
