Download ROS Legacy for PC from the operator URL https://dl.roslegacy.net/full. That address currently serves ROSLegacy_Install_202609251811.zip, 8,251,115,387 bytes, about 8.25 GB. The file lands on edge.roslegacy.net after the redirect. roslegacy.net's Download for PC button points at this same endpoint. There is no Steam depot and no third-party mirror on the official page. If a guide still lists dl.mythgames.net/rosl/full, that URL now 404s.

Windows install checklist
1. Open the operator zip
Use https://dl.roslegacy.net/full only. Confirm the filename ROSLegacy_Install_202609251811.zip before you run it.
2. Budget 8.25 GB
The live package is 8,251,115,387 bytes. A much smaller zip with the same title is not this installer.
3. Register after the client lands
Create the Mirae Labs ID on the Register page. The client expects that account, not a NetEase login from 2018.
What the Windows endpoint actually serves
Download for PC on roslegacy.net is a same-site control that hits https://dl.roslegacy.net/full. A HEAD request on that URL follows to edge.roslegacy.net and reports ROSLegacy_Install_202609251811.zip. The byte size 8251115387 is the operator figure to check against your downloads folder. Play Free Now on the homepage does not start a different file; it scrolls to this same download block.
The zip is an Open Beta full installer, not a tiny launcher stub. Plan disk space before you click. The official site does not publish a CPU, GPU, or RAM table, so no invented spec sheet belongs here. If the client fails to start, the next useful check is whether you installed this zip rather than a renamed archive from a video description.
Android players should leave this page and use the Mobile APK instead of forcing the Windows zip onto a phone. iOS remains Coming Soon. Steam store search for ROS Legacy still returns zero products, so there is no Steam install button to prefer over dl.roslegacy.net.
A healthy Windows install is boring: one zip, one filename, one host. After the unpacker finishes, launch the client, sign in with the Mirae Labs ID, and only then look for friends on Discord. Skipping the account step is the usual reason a first launch sits on a login screen that looks empty.
If the zip is still downloading after a long session, check that Windows did not drop the transfer. Resume from https://dl.roslegacy.net/full rather than grabbing a "finished" copy from a friend. Byte size 8,251,115,387 is the check against a truncated download.
The Windows zip is a full Open Beta package, so antivirus may scan it for several minutes. Let the scan finish. A truncated copy that you renamed to ROSLegacy_Install_202609251811.zip is still truncated. If the client asks for another download, go back to https://dl.roslegacy.net/full instead of accepting a helper exe from a pop-up.
After the zip extracts, launch from the new folder rather than from a desktop shortcut someone else mailed you. Shortcuts can point at an old Myth Games path that now 404s. If Windows SmartScreen warns, compare the publisher path to edge.roslegacy.net. A warning on a random helper named setup.exe is a different event; delete that helper and keep the operator zip.
If the zip is already on disk from last week, check the filename before you run it. ROSLegacy_Install_202609251811.zip is the live operator package. An older zip with a 2025 stamp is a different build. Delete the older one so you do not launch it by habit. Then run the live zip, sign in, and only then invite friends.
Why third-party PC packs are the wrong file
roslegacy.net does not link Google Drive, MediaFire, or "repack" hosts. Those pages often reuse the ROS Legacy name on an older Myth Games build or on unrelated executables. The retired Myth Games full-installer URL https://dl.mythgames.net/rosl/full returns HTTP 404, so even the former operator path is dead.
If a Discord stranger pastes a shortened link, compare it to https://dl.roslegacy.net/full before you run anything. Filename drift is normal when Mirae Labs ships a newer zip; the host should still be dl.roslegacy.net or edge.roslegacy.net. A host outside roslegacy.net is not this Open Beta.
After the Windows client is in place, finish the account step on Register, then read the beginner guide for SOLO, DUO, and SQUAD. Questions about whether the game is out belong on Release date and the FAQ.
Video descriptions are a common place for stale Myth Games links. If the URL host is mythgames.net, stop. If the URL host is a shortening service, expand it and compare to dl.roslegacy.net. The official homepage never prints a Google Drive ID for this installer.
After you confirm the zip, you still need disk space for the unpacked client, which is larger than the archive. Keep the zip until the client launches once. If Mirae Labs ships a newer filename, replace the whole package from dl.roslegacy.net/full instead of mixing folders from two zips.
LAN-sharing the zip with friends is fine if you all started from the operator URL and the byte size matches. LAN-sharing a folder that also contains a random trainer is not. Wipe the folder and fetch the zip again. Then create the Mirae Labs ID if you have not already.
Treat the Windows desk as a three-field record: URL https://dl.roslegacy.net/full, filename ROSLegacy_Install_202609251811.zip, size 8,251,115,387 bytes. If a helper site matches two of those three and misses the host, reject it. After a successful launch, you can delete the zip to save space, but keep the operator URL. The client will not turn into a Steam game while store search still returns zero products. If you dual-boot, install on the Windows partition, not on an Android emulator, unless you intend to use the APK path instead. When the Open Beta client patches, prefer a fresh operator zip over copying a friend's already-patched folder, because mixed files are the usual source of mystery crashes in a public beta.
The PC desk is finished when three things are true: the zip came from dl.roslegacy.net/full, the client launches, and Mirae Labs login accepts the ID. Anything after that is play, not install. If only two of the three are true, fix the missing one before you blame the storm. A launched client with no ID is an account problem. An ID with no client is a download problem. A client that is not the operator zip is a mirror problem. Those three problems have three pages: Register, this Download page, and the mirror warning on this same page.
Keep https://dl.roslegacy.net/full in a note on your phone so a friend can fetch the same zip without a screenshot of a random Drive folder. The operator URL is the whole PC safety rule.
