Requirements

  • Windows 10 or 11, 64-bit
  • About 500 MB of free disk space
  • An internet connection
  • A microphone for voice channels (optional)
  • A good upload connection to stream at 1440p60

How to install

  1. Download the Zync-Setup-0.9.3.exe installer.
  2. Open the file. If Windows shows a warning, see below.
  3. Zync installs in one click, without asking for administrator rights, and opens by itself. Create your account or sign in.

Updates

Zync downloads new versions in the background while the app is open. When one is ready, an Update button appears in the title bar; if you do not click it, the update installs when you close the app. No need to download again here.

Windows showed "Windows protected your PC"

During the beta, the installer is not code-signed yet. That is why Windows SmartScreen warns on first run — the same warning any new program without a certificate gets.

  1. In the blue window, click More info.
  2. Check that the file is Zync-Setup-…exe and click Run anyway.

Want to check the file is the original?

Compare the hash of the downloaded file with the SHA-512 published above. In PowerShell, in your Downloads folder:

$f = "$PWD\Zync-Setup-0.9.3.exe"
[Convert]::ToBase64String([Security.Cryptography.SHA512]::Create().ComputeHash([IO.File]::OpenRead($f)))

The result must match the SHA-512 on this page exactly. Only download Zync from usezync.com.

Other systems

macOS, Linux, a web version and mobile are on the roadmap, after the 1.0 launch on Windows.
