These URLs are the ones Transmission Project declares in its own manifest. We do not proxy or shorten them, and we do not host a copy.

More than one architecture below. Check which one your Windows is if you are not sure.

Verify the file you downloaded

Run this against the file on disk. If the output does not match the hash below, the file is not what Transmission Project published. Delete it.

Windows · PowerShell

Get-FileHash "transmission-4.1.3-x64.msi" -Algorithm SHA256

macOS · Linux

shasum -a 256 "transmission-4.1.3-x64.msi"

Expected output

Got a different hash, or one you cannot place? Paste it into the hash checker and it will tell you which program and version it belongs to, past releases included.

Install Transmission silently

This installer is an MSI package, so it takes the standard Windows Installer switches. That is a property of MSI itself rather than something the publisher declared.

32-bit · machine scope · MSI convention

msiexec /i "transmission-4.1.3-x86.msi" /qn /norestart

64-bit · machine scope · MSI convention

msiexec /i "transmission-4.1.3-x64.msi" /qn /norestart

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.

Uninstall Transmission cleanly

Every guide on this tells you to hunt for the product code with Get-WmiObject or in the registry. You do not need to: it is published in the installer manifest, and it is printed below.

Product code · 32-bit

{9A6FE859-BC52-4324-B99A-9F8670C4F55B}

Uninstall, with the usual prompts

msiexec /x {9A6FE859-BC52-4324-B99A-9F8670C4F55B}

Silent, for deployment

msiexec /x {9A6FE859-BC52-4324-B99A-9F8670C4F55B} /qn /norestart

Product code · 64-bit

{6F8D6CC5-B77E-4803-8EFA-34509F53360F}

Uninstall, with the usual prompts

msiexec /x {6F8D6CC5-B77E-4803-8EFA-34509F53360F}

Silent, for deployment

msiexec /x {6F8D6CC5-B77E-4803-8EFA-34509F53360F} /qn /norestart

The product code changes with every version

The codes above belong to Transmission 4.1.3, the version in our index. If you have an older release installed, its code is different and this command will report that the product is not installed. In that case run Get-Package -Name "Transmission*" in PowerShell to read the code of what you actually have.

This removes the program as the publisher packaged it. Settings and files created after installation, typically under AppData, are deliberately left behind by the uninstaller and have to be deleted by hand if you want them gone.

Reinstalling and hitting error 1638? That is this same product code, and the command above is the fix.

Download Transmission for Mac

The macOS build as Homebrew declares it, with the same treatment as the Windows side: the publisher's own URL and a hash to check it against.

Is Transmission safe to download?

The installer comes from a recognised distribution platform rather than Transmission Project's own domain. That is normal for this kind of software and not a red flag by itself.

Every one of the 2 installers on this page comes with the SHA-256 Transmission Project 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 95/100 score is calculated · why the source matters more than the reputation

Install Transmission with winget

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 Transmission.Transmission --exact

Upgrade later

winget upgrade --id Transmission.Transmission

Why --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.

Old versions of Transmission9 with hashes

The version history of Transmission, 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.

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.
