Notepad++ 7 - 64-bit Available

  • @Salimsg-Ibrahim i just wanted to point out the same solution, i found it on myself

    In regedit: Navigate to Computer\HKEY_CLASSES_ROOT\Applications\notepad++ and find your .exe name.
    Navigate under its name to shell>open>command. In the Default change its location to the actual location of the executable, hit okay and then try and reassociate the file type as you normally would.

    @donho i fear there will be a lot of users experiencing this problem, maybe you should try to get a fix before the automatic update causes a lot of troubles

    i like @dail solution

    • During installation (e.g. of 64bit Notepad++ version)
      • Check to see if 32bit version is currently installed.
      • If so, warn the user that installing both may cause problems.
      • Ask the user if they want to uninstall the 32bit version.
      • During uninstall of 32bit version, give the user the option to keep their current settings. This would probably be easy if they are using %APPDATA% but if they are using a local conf mode then the xml files won’t be in the right place, they would be under C:\Program Files (x86)\...

  • More ported plugins:

    Same issue

  • @Sean-McPoland

    The plugin manager has been left out of the 64-bit version of Notepad++ because a 64-bit version of the plugin manager does not exist. And you are correct that very few 64-bit plugins currently exist.

  • I found an interesting issue. When the “Commonad Argument Help” window is kept open,press Ctrl+S in the editor window will insert a special character, which is shown as a black background, white foreground block with the label ‘DC3’.

  • Lazy question before I try it: Does Notepad++ 64 bit support larger file size than Notepad++ 32 bit?

    I have been using Notepad++ to convert large files of UTF-8 text data to UCS-2; they start around 450,000,000 bytes size and end up about 900,000,000 bytes. (There are other ways to do that, which I don’t have access to in my test environment, e.g. PowerShell 5.0 has capabilities.)

    Notepad++ saves the larger file but then cannot open it - I assume this is not a flaw in my environment. I would like to be able to open the file and save it back to UTF-8. This should be identical to the original file, but that is what I want to test.

    in theory yes, but at the end it depends how many ram can be used.


  • Without plugings for x64, it’s a pity…

  • @БлагоѨръ-Тишина̀

    come on, it’s brand new - plugins need to be developed/recompiled etc…
    and even without any plugins, npp is still a fast and powerful editor.


  • The Windows 10 association function setting is invalid.

  • @Robert-Carnegie
    Notepad++ (or the Scintilla component?) seems to use significantly more memory when styling is activated for the document. And it is much slower. Deactivate text styling before opening huge files or rename the file extension to an unassociated file extension, like *.xyz

  • I’ll just add a me too to this one.
    If you install NP 64-bit over the top of NP 32-bit then you can’t uninstall both.
    Uninstall either 32-bit or 64-bit and both references are removed from ‘programs and Features’
    there is also no way of telling of distinguishing between 32 and 64 bit versions in Programs and Features.

    This was on Windows 10 Version 1607, but I suspect that ain’t going to make too much difference.

    thanks in any case for the port to 64-bit.

  • I stay in 6.9.2 are equal. Macro recording does not work

    I’ve seen some uninstallers ask the user whether they’d like to keep their configuration files. Not sure how easy this would be.

    I’m doing this feature. it’ll keep config.xml, stylers.xml, langs.xml, contextMenu.xml and themes files (all the files in %APPDATA%\notepad++).
    A message box with Yes and No buttons will be launched during the uninstallation. for asking users if they want to keep their user data.
    Any suggestion about the message in this box?

  • @donho I’m glad to hear it :)

    Any suggestion about the message in this box?

    I think a simple message would suffice, something along the lines of: “Would you like to keep your custom settings?”

  • Hi,

    The bug is still there in version 7.1.

    This is working and the installtion will be i the folder C:\Pub
    npp.7.1.Installer.exe /S /D=C:\Pub

    The x64 version of 7.1 is not working.
    The installtionfolder will be C:\Program Files\Notepad++
    npp.7.1.Installer.x64.exe /S /D=C:\Pub
    When will you fix this bug???


  • @Dave Tabz would like to when the 64bit pugin manager version will be ready

  • Perhaps add some info about why to use 64-bit version.
    Why should users choose the 64-bit version instead of the 32-bit version and vice versa.

  • @donho FYI, I just installed Notepad++ 7.3.2 64-bit version where there had been Notepad++ 7.3.2 32-bit version and it warned me about removing the 32-bit version while noting it would preserve settings.

    I have done this several times since my original post - thanks for the changes to accommodate this.

    However in this case I then ended up using the View Source command in Internet Explorer and got this error:

    [Window Title]
    C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

    Windows cannot find ‘C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe’. Make sure you typed the name correctly, and then try again.


    Turns out the 32-bit installer had set this value at some point in the past in the registry and it was not modified or removed when I ran the 64-bit installer:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\View Source Editor\Editor Name
    (Default) = C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

    Since the 32-bit program is removed, there is no C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

    Further there is no 64-bit version of nppIExplorerShell.exe in C:\Program Files\Notepad++

    You can, of course, replace the default value with “C:\Program Files\Notepad++\notepad++.exe” and IE will launch npp as the viewer although it will likely throw a security warning.

  • I literally only just found out Notepad++ has a 64-bit build. Sadly I switched to Sublime Text back in 2015 when I really needed a 64-bit editor to handle the monster text files generated by FEA software (Abaqus and HyperMesh, specifically) that Notepad++ choked on. Sublime has Linux builds also and a native, default dark theme, sooo gonna stick with that. Bittersweet though, because Notepad++ was one of my favorite apps right up to the point it couldn’t do what I needed it to :(
