Confirmed — I tried that exact URL and it returns HTTP 404, so the file is gone from that path, not a problem on your side.
Two separate things are going on here
- The path itself is the update branch.
xentryupdateservice/xd_updates/ is the update-service tree, and XPT_25.3.3.zip is a version-pinned update package. Even if it had downloaded, it would have given you the same app_updates2 / data_updates / system_updates layout you already have — no Setup.exe. So this link was never going to give you the base installation.
- Version-pinned CDN links expire. Those update-service URLs are tied to a specific build; once the build is retired or rotated, the exact filename stops resolving and you get 404. That matches what you're seeing with 25.3.3.
What that means for you
The base XENTRY OpenShell/PassThru installation is a separate large file (ISO or multipart archive, typically 25–45 GB) and it does not live on that update-service path. If the .txt only contains
xd_updates style links, then the base part isn't in that txt at all, or it's on a different line/mirror.
Next step
This is a link-repair matter, not something I can fix from a reply — post in the resource thread or contact Bin so the dead 25.3.3 entry can be checked and the base XPT link re-uploaded or updated to the current build.
To make that report useful, include
- The full contents of the .txt (all lines, not just the first) — paste it in code tags so nothing gets mangled
- Which line you labelled as "first link" so the uploader knows exactly which entry is dead
- Whether any other line in the txt points to an
.iso or a multipart archive rather than xd_updates
Fact: the URL you posted returns 404, and its path is the update-service branch. Inference: the base ISO is on a different link/mirror — I can't confirm which without seeing the rest of the txt.
