What this site is
OfflineInstallerSetup is an independent directory that points people to the official source for downloading desktop software. We do not host files, and we are not affiliated with the publishers we list. Our value is curation and honesty: we find the publisher’s real download, describe it accurately, and send you straight there.
What we check on every page
- 1
Confirm the publisher’s official domain
Every entry starts from the software’s own website — found through its Wikipedia article, its source repository, or the developer’s verified social profiles, not a search-ad result. We record that domain as the single source of truth for the listing.
- 2
Resolve the real download target
We open the publisher’s download page and follow it to the actual file or the page the publisher serves. If the publisher exposes a direct installer file (.exe, .msi, .dmg, .pkg, .deb, .rpm, .AppImage, .tar.gz), we capture that URL. If they only offer a download page or require a sign-in, we link to that page and label it honestly — we never invent a direct-file URL.
- 3
Check the file type and platform
We record which platforms the publisher actually supports and the package type per platform. We do not claim macOS or Linux support a publisher does not offer, and we do not call a web-bootstrapper a “standalone offline installer.”
- 4
Capture version and size from the source
Version and file size are taken from the publisher’s release, not estimated. When a publisher does not state a size, we leave it blank rather than guess.
- 5
Re-check on a schedule
Listings are reviewed and refreshed on an ongoing basis. Because we link to the publisher’s own page, you always reach their current release even between our reviews. If a link breaks, a reader report or our own re-check catches it and we fix or remove the entry.
What “official source” means here
A source is “official” only when it is controlled by the software’s publisher — their own domain, their own repository on a recognized code host, their own app-store listing, or their verified distribution mirror. A page that merely offers the software is not official unless the publisher runs it. Where a publisher’s only download requires a sign-in or a purchased key, we say so on the page rather than implying a free, direct file exists.
What we will not do
- ✕ We do not host installer files. Every download leaves our site and lands on the publisher’s own infrastructure.
- ✕ We do not wrap downloads in our own installer, “download manager,” or ad-gate.
- ✕ We do not use third-party mirrors, crack sites, or key generators as sources.
- ✕ We do not publish fabricated download counts, star ratings, or “verified hourly” stamps we cannot prove.
- ✕ We do not claim an app ships an offline/standalone installer unless the publisher actually provides one.
- ✕ For software a publisher no longer distributes (e.g. end-of-life Windows releases), we say so plainly instead of linking to an unofficial copy.

Found a problem?
If a link doesn’t reach an official source, a version looks wrong, or anything reads as inaccurate, please tell us. We treat sourcing corrections as the highest-priority fixes and update or remove the entry quickly.
