Deno for Windows 7/8 ?

Unread post by **Duke** » 18 Nov 2025, 14:04

When I'm using Deno with yt-dlp on Windows 8.1 I'm getting this error message:
"The procedure entry point IsWow64Process2 could not be located in the dynamic link library Deno.exe"

After some investigation it looks like IsWow64Process2 is only available on Windows 10 1809 and higher.
Is there a workaround or a build for Windows 7 & 8 ?

I'm really starting to feel like the internet would die out and fade into existence without "yt-dlp".

QuickJS option here works fine

Thanks, I'll give QuickJS a try.
Which build are you using ? This one https://github.com/quickjs-ng/quickjs/releases or this one https://bellard.org/quickjs/binary_releases/?C=M;O=D ?

I've tried Fabrice Bellard's one, a well known guy you can trust, and it's working pretty fine

Thanks for the tip

Plus it's only 920 kB vs 112 MB for Deno.
