    Maybe your compiling links newer DX libs that not supporting xp. I would guess it is due to the DX lib when you compile Qt, as I said.

    You mean i should install Directx9 on my windows7, remove all other DirectX versions and compile qt5.6.3 again?

    You may be able to compile only the dsengine plugin.
    But I don't know how to make sure you link the xp supported DX lib, since I don't target xp for at least 5 years...

        Hi, one other thing I saw in the dependency walker's output, it wants the Qt files from another Qt directory on your XP machine:
        c:\tools\neovim\neovim\bin

        Make sure that this other version exists and is also Qt 5.6.3 Release for MSVC 2013.

          Hello. I have some questions:

          1. Why application loads these .dlls from that weird directory instead of current directory of my application? (I used windeployqt)
          2. Lets say, i fixed it. Do it fix main issue?(Showing video)

            Hi
            1: Ask Windows :) It is its run time loader that controls this.
            2: It could fix it. However, the normal effect of mixing Qt version is crashes so
            dont get to much hope up.

              @mrjj I mean why it didn't look in current directory first, if it looked why doesn't load it? Since those dlls exists beside main exe file.

              I noticed that on windows xp that doesn't have this directory(c:\tools\neovim\neovim\bin\), DependencyWalker complains that it can't find dlls:
              depXP.PNG
              `

                Well back in the Xp days they didn't load better i guess.
                In the newer version of windows, you can add a manifest file to tweaking it and at some point they also allowed
                side by side loading of Dlls with same name etc.
                https://docs.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-order

                well (c:\tools\neovim\neovim\bin) seems just to be
                https://github.com/neovim/neovim
                but it does uses Qt for GUI .

                Hmm so the DSENGINE cannot find its support DLLS ?
                those missing files are in your app folder ?

                Is there a reason you cant use a virtual machine with Xp (or real pc ) to install Qt5.6
                and what ever compiler you wish and simply compile and xp version for xp.
                And compile a win 7+ on win 7 ?
                Im not 100% sure you can have a one .exe that works on both as the backend changed alot.

                  Exactly.

                  I tried to compile qt 5.5.0 on windos xp.(It's a virtualbox machine). It complains about some functions that only exists on x64 architecture.

                  Im not 100% sure you can have a one .exe that works on both as the backend changed alot.

                  So, you mean i should compile whole application in each os separately?

                      Well that is how a few people I know still do - to have xp version. Its only SP3 Xp's that works but I guess
                      all remaining xp's are patched.
                      It might be less work than to make sure it links to older directX in newer windows. (if thats even possible)

                        Yes. I saw someone write he used that version in 32 bit and it worked for
                        Xp. I didnt personally tried it, though.
