Who here has a Youtube-DL compile for WinXP?

[nicolaasjan]

By the way, during building the XP version, I get these warnings:

8852 WARNING: lib not found: fileextd.dll dependency of C:\Python311\KERNELxp.dll
8882 WARNING: lib not found: kernelex.dll dependency of C:\Python311\KERNELxp.dll

so I took that to mean: 

1. You're gonna use adang1345's "CPython-3.14.0-win32" build to compile them, which is Vista+ compatible 

2. Use the special, Vista-compatible, build of PyInstaller-6.15 (by 3dyd) to produce the standalone "yt-dlp_x86_win7.exe" binaries (as I believe was the case when preparing recent 3.13.7-based binaries) ...

Why did you change plans ?

Thanks again for your time and efforts  ...

I use adang1345's Python builds for both x86 and x86-64 builds.

I have PyInstaller 6.16.0 for both and I can't remember having used PyInstaller 6.15 (by 3dyd) before this latest build for Win7...

Btw, that `K32EnumProcessModules` error also happens on Vista when building with the latest Python 3.13.8 from adang1345 and PyInstaller 6.16.

Maybe you could ask adang1345?

Do you want me to "downgrade" to that custom PyInstaller (for the Win7 builds)?

I think that must be because I built directly after the standalone one, i.e. without deleting the build directory and start over.

After I built the `onedir` version today from a fresh source directory, I got:

[debug] yt-dlp version nicolaasjan/yt-dlp@2025.10.13.080600 (win_x86_dir)
[debug] Python 3.11.4 (CPython x86 32bit) - Windows-XP-5.1.2600-SP3 (OpenSSL 3.5.2 5 Aug 2025)

Thanks for the prompt explanation  ; I'm probably being obsessive-compulsive here  , but can you share the fixed "yt-dlp.exe" binary (I think that one only should suffice) inside the fixed (today's) "yt-dlp_x86_winXP.zip" archive? Many thanks indeed...

Testing previous "yt-dlp_x86_win7.exe" assets from GH, 

https://github.com/nicolaasjan/yt-dlp/releases/download/2025.09.23.052315/yt-dlp_x86_win7.exe

doesn't launch under Vista SP2 32-bit ("K32EnumProcessModules" error); this one uses adang's CPython-3.13.7-win32 implementation.

Both the next two following releases, 

https://github.com/nicolaasjan/yt-dlp/releases/download/2025.09.27.071342/yt-dlp_x86_win7.exe

https://github.com/nicolaasjan/yt-dlp/releases/download/2025.10.05.061237/yt-dlp_x86_win7.exe

launch fine here (Vista SP2 32-bit, see also my previous post); these two also use adang's CPython-3.13.7-win32 implementation. You've told us you build yourself the "win7" assets manually and then upload them to GH; so, what was the change between v2025.09.23.052315 and v2025.09.27.071342 in your building env that enabled Vista support for the latter (and the one after it) ? Likewise, what was the change, besides the CPython upgrade from 3.13.7 -> 3.14.0, that removed Vista support in 

https://github.com/nicolaasjan/yt-dlp/releases/download/2025.10.13.080600/yt-dlp_x86_win7.exe ?

IMHO, this is not the root cause; see my comment just above about "v2025.09.23.052315 vs v2025.09.27.071342"; in any case, he's just providing a Vista-compatible Python interpreter, fixing the various Python modules shouldn't be his concern  ...

My impression so far about the PyInstaller Python module is: 

1. PyInstaller==5.13.2 is the last one which produces XP+Vista compatible packages; but this one doesn't support py>3.12

2. PyInstaller >=6.0.0 target by default Win7+ systems (ofc, I haven't tested myself all individual versions 6.0.0-6.16.0); they say so on the module's PyPI page: 

Quote

Windows (32bit/64bit/ARM64):

PyInstaller should work on Windows 7 or newer, but we only officially support Windows 8+.

So, my educated guess is that v6.16.0 produces, by default, Win7+-compatible binaries (but does this "default" depend on the actual OS the module is being run on? Have you tried building the "win7_x86" variants on a Vista VM with adang's CPython?)

3dyd's PyInstaller==6.15.0 fork is special in that it makes sure the produced binary retains NT6.0 support, because: 

https://github.com/3dyd/pyinstaller-builds/blob/d1a786dcb4316557df3c97f14e16cac7092b744c/.github/workflows/build-package.yml#L44

CFLAGS=-DPSAPI_VERSION=1 LDFLAGS=-lpsapi python waf all --target-arch=32bit --gcc

where "CFLAGS=-DPSAPI_VERSION=1" is the crucial configuration! That is why I was, up until now, under the impression the working v2025.09.27.071342 and v2025.10.05.061237 yt-dlp_x86_win7.exe binaries had been compiled with 3dyd's PyInst mod...

Right now, "we" should get to the bottom of this conundrum; but my clairvoyant skills are limited here; I've already described all I could think of  ; as for using 3dyd's mod for the "win7" assets (since you're adamant you haven't used it until now), this won't hurt at all the Win7 users; plus, GH offers some extended retention of previous builds (10 last), whereas the dropbox "Vista" links expire/404/change etc., with the newer "Vista" build overwriting the previous one... As for the "downgrade", we can always nudge 3dyd for a newer build, though your previous request in his tracker has been standing idle thus far ...

Thanks again (and really sorry for being a PITA ) ...

I'll send the whole zip file.

  ; and as I had suspected, just the "yt-dlp.exe" file was enough  ; and if you

1. delete the 4 wrapper DLLs targeting XP (kernelxp.dll, ntext.dll, psapi.dll, ws2_xx.dll)
2. substitute files python311.dll, _overlapped.pyd, _socket.pyd with their Vista counterparts (thanks, cmalex ), you can even run the "onedir" distribution under Vista SP2 32-bit:

I'm sorry. I have no idea...

Yes, that is the special yt-dlp_Py3.14.0_x86_Vista.

True, but maybe he has an idea.

I'm as puzzled as you are in this case...

In the meantime, I'll use the 3dyd PyInstaller the next time for the Windows 7 builds.

[nicolaasjan]

Can you test this Win7 build: yt-dlp_x86_win7.7z ?

Built with adang1345's Py3.14 with custom PyInstaller 6.15 on Windows 10.
