NPP v6.6.9 last W2K version? ohh no! All update >v6.7 don't run under W2K

  • Hello,

    all version over 6.6.9 don’t run under W2K.

    why not?

    The Win32-Installer (v7.2.3) install und run = OK

    and start npp.exe … error message: “npp is not a valid win32 application”

    Can someone help me?

    ps: … and the setup/installer should check the supported OS.

    Thanks and best regards,

  • You could always try to get the simple zip file and unzip it wherever you’d like. Maybe that will work on W2K.

  • Hello Jim,

    thanks for your answer.

    I’ve tried auto-update in npp, install.exe and manually with .7z.

    Unfortunately doesn’t work.

    All versions >= v6.7 don’t work with Win2000. (I have tested with two Win2000-systems)

    Error message: “notepad++.exe is not a valid win32 application”

    (sorry, for my bad english ;-)

    Thanks and regards,

    It may be time to let go of Windows 2000. I mean, it was great and all, but…

  • @Alan Kilborn
    thank you for your answer. But, please no discussion for and again an OS system.

    Win2000 is lean, stable and working. Reset only once a year … has been running for over 16 years.

    DOS: 1 + 1 = 2
    AmigaOS: 1 + 1 = 2
    Win95: 1 + 1 = 2
    NT4: 1 + 1 = 2
    OS/2: 1 + 1 = 2
    MacOS: 1 + 1 = 2
    W2K: 1 + 1 = 2
    XP: 1 + 1 = 2
    W7: 1 + 1 = 2
    W10: 1 + 1 = 2
    ohhh … Linux: 1 + 1 = 2
    and so on … all results are the same :-)

    Sorry, but your answer is not intended for me.

    There may be only two small source changes between 6.6.9 and 6.7, which can be responsible for this problem.

    Unfortunately I have no compilation environment for npp and can not compile “trail & error”. I have installations only Delphi7 / FreePascal. ;-)

    Just curious, what is all the 1+1 = 2 stuff ?? I don’t get it…

    In case you didn’t see this other post recently, the author of Notepad++ has hinted (I think, if I am reading his posting correctly) that the 32-bit build of N++ has very-limited life left.

    Can your Windows2000 run 64-bit executables?

    Good luck to you. :)

  • @Alan-Kilborn

    I think the 1+1=2 stuff is the OP’s way of saying that all these OSes are equivalent, i.e., they all add 1+1 the same. Other than that, I have no comment on this thread. :)

  • all version over 6.6.9 don’t run under W2K.
    why not?

    Because honestly at some point backwards compatibility is dropped in order to take advantage of newer features to provide a better tool for the majority of users.

    v6.6.9 was release in 2014…that is 14 years of support for W2K…which is quite a long time if you ask me. If you choose to run an older OS (which by all means is your choice) you shouldn’t be surprised when new software doesn’t support it.

  • Personally I think that Win2K was the greatest OS Microsoft has ever produced.
    Microsoft tried to kill it as quickly as they could because of the very important missing feature “activation”.
    Now, there shouldn’t be a technical reason for not supporting Win2K. Notepad++ tech is just legacy enough to fit it perfectly. But …
    Microsoft current compilers and DLLs are no longer compatible. At least by default. It probably should be possible to compile current 32 bit Notepad++ for W2K, but it will take an effort to tweak the build tools. And nobody is going to do it or even bother to install Win2K to test it.

    But Notepad++ is open source. Feel free trying to build it on your own.

    One small additional comment. From experience I know that NPP added use of some advanced C++ that is not supported by W2K era compilers. It does not mean that new compilers can’t be forced to produce W2K compatible binaries but it makes things more difficult.

    Seems VS2008 is the last dev studio providing win2k support.

    Currently used VS2013 just supports builds for WIN XP SP3 and newer.

    Maybe mingw64 builds would still be compatible.

    If someone has a chance to build it, I am willing to test Notepad++ under Win2k. We still have a couple of machines running this OS, and no easy way to upgrade them.

    I confirm that Notepad++ 6.6.9 is the latest to work under Windows 2000, although it does not work right out of the box. The reason: it comes with plugin NppFTP version, which is too new. The solution is to disable this plugin, or downgrade it to version

    Agreed! I could test as I have a win2k machine handy but after looking into what’s needed there’s too much pain involved.

    The hassle is that it npp is compiled with Visual Studio.

    I verified the OP’s finding using the .7z packages that 6.6.9 is the last version that works on Win2k. The nppFTP plugin blows up but once that’s disabled then npp 6.6.9 works fine.

    npp 6.7 fails to start with “npp is not a valid win32 application.” The process is not even launched.

    I checked the PE headers.

    v6.6.9 will work on Windows NT
        8.0 linker version (compiled with Visual Studio 2005)
        4.0 operating system version
        4.0 subsystem version

    v6.7 will work on Windows XP on up.
        12.0 linker version (compiled with Visual Studio 2013)
        5.1 operating system version
        5.1 subsystem version

    Windows NT is version 4.0, 2000 is version 5.0, XP is 5.1, and 2003 is 5.2.

    Microsoft dropped support in the Visual Studio CRT as APIs such as HeapSetInformation() were added in Windows XP that are useful enough to the CRT that Microsoft chose to just bail-out rather than trying to work around not having those functions available.

    Ideally, Microsoft would have added HeapSetInformation() and related APIs to Kernel32.dll via Windows Update but then there never would be a reason to buy an newer operating system version.

    One workaround that may work is to compile with VS2013 but to link with VS 2005.

    Unfortunately, SciLexer.dll may also needs to be compiled/linked the same way. It’s requesting a minimum operating system version of 6.0 which is Windows Vista.
