Razer Synapse 3 · earlier release

Razer Synapse 3 1.15.0.504

The URL Razer Inc. published for this release, and the SHA-256 of every file in it, so you can prove the copy you have is that one and not something else wearing the same name.

Released 18 December 2023.

This is not the current release

Razer Synapse 3 is now on version 1.22.0.737. An older build stops getting security fixes, so install one only when you have a reason: a plugin that broke, a machine that cannot run the new one, a bug you need to reproduce. If you just want Razer Synapse 3, take the current version.

Files in Razer Synapse 3 1.15.0.504

Check the file you have

Windows does this without installing anything. In PowerShell:

Get-FileHash .\RazerSynapseInstaller_V1.15.0.504.exe -Algorithm SHA256

Compare what it prints with the value above. If they match, your copy is byte-for-byte the one Razer Inc. published. If they do not, it is a different file, whatever it is called and wherever it came from. Paste a hash into the verifier and it will tell you which release it belongs to.

If PowerShell is blocked by policy on the machine, the same thing works from plain cmd with certutil -hashfile RazerSynapseInstaller_V1.15.0.504.exe SHA256. On macOS or Linux it is shasum -a 256 RazerSynapseInstaller_V1.15.0.504.exe.

If the link no longer works

Publishers retire old releases, and we do not host copies, so a link from an earlier version can stop working without notice. Two ways it fails: an honest 404, or — more confusing — the server answers normally but hands you the current downloads page instead of the file. If what arrives is a few kilobytes of HTML rather than an installer, that is what happened.

The hash on this page stays useful either way. It still identifies Razer Synapse 3 1.15.0.504 wherever you find a copy, which is the whole point of publishing it: you can accept a file from somewhere else and still prove it is the one Razer Inc. built.
