The free global standard for reliably viewing, printing, signing, and commenting on PDF documents.
Adobe's normal download path hands you a small Reader DC web installer and, along the way, tries to add extras you did not ask for. The offline installer is the full MSI-based package, which is also what you want for deploying Reader across an organisation.
The installer on this page is the full standalone build declared in Adobe's manifest, so it does not download anything further during installation.
Because it registers a product code, it uninstalls cleanly and can be managed through standard deployment tooling, which the web installer does not do reliably.
Adobe's web download page has historically pre-ticked additional software. The standalone installer avoids that path entirely, which is a good reason to prefer it even on a machine that has internet.
These URLs are the ones Adobe declares in its own manifest. We do not proxy or shorten them, and we do not host a copy.
Run this against the file on disk. If the output does not match the hash below, the file is not what Adobe published. Delete it.

The unattended switch below is the one Adobe declares in the installer manifest, not one we guessed by trying flags.

.\AcroRdrDCx642600121789_MUI.exe -sfx_nu /sAll /rs /msiAdobe’s switch is unusual because the file you download is a self-extracting wrapper around an MSI. The declared command unpacks it and hands the MSI its own quiet flags in one step, which is why it looks nothing like a normal silent switch.
If you want control over what gets installed, extract first rather than fighting the wrapper. Running the installer with -sfx_o"C:\path" -sfx_ne unpacks the MSI and its transform without installing, and from there it is an ordinary msiexec deployment.
Adobe publishes a Customization Wizard that produces an MST transform: it is how you disable the updater, accept the EULA in advance, suppress the sign-in prompt and turn off the upsell for Acrobat Pro. Applying the transform with TRANSFORMS= is the difference between a deployment users complain about and one they never notice.
Without EULA_ACCEPT=YES the first launch shows a licence dialog to every user, which defeats the point of deploying it silently. Set it in the transform or on the msiexec command line.
Adobe’s update service runs regardless of your patch process and will change the version underneath you. Disable it through the Customization Wizard if you manage updates centrally.
Run it from the folder holding the downloaded file, in a terminal opened as administrator when the package installs for all users. Silent means no window and no prompts, so check the exit code rather than waiting for something to appear: 0 is success and 3010 means it worked but wants a reboot.

Extensions Adobe Acrobat Reader (64-bit) registers itself to handle.
Yes, in the sense we can actually verify: the installer downloads from adobe.com, which is a domain we have tied to Adobe.
The installer on this page comes with the SHA-256 Adobe declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.
How the 100/100 score is calculated · why the source matters more than the reputation
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id Adobe.Acrobat.Reader.64-bit --exactUpgrade later
winget upgrade --id Adobe.Acrobat.Reader.64-bitWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
The version history of Adobe Acrobat Reader (64-bit), each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

The file names, so you can tell what you have. Their hashes are in the hash checker and in the downloadable archive.
Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
Every Adobe Acrobat Reader (64-bit) version with a published manifest, newest first. The most recent ones are listed above with their file names and hashes.
Matched on the categories Adobe and others declare in their own manifests, so the grouping is theirs rather than ours. Each one has its official URL and hash on the same terms as this page.
