Free to download. A license key is required to activate — purchase one from the screensaver pricing page if you don't have one yet.
Follow these steps after the installer downloads
Double-click CallaStreamScreensaver-Setup-1.0.5.exe. If Windows shows a SmartScreen warning, click "More info" then "Run anyway" — this appears because the app is not yet code-signed.
Follow the installer prompts. The screensaver installs to C:\Program Files\CallaStream Screensaver\ and registers itself as a Windows screensaver automatically.
The activation window will appear automatically. Enter your license key (CS-SCR-XXXX-XXXX-XXXX) from your purchase confirmation email and click Activate.
Log into your CallaStream dashboard at callastream.com/dashboard-v2. Your screensaver device will appear in the device list — click Assign to choose what it displays.
The screensaver will activate automatically when your PC goes idle. By default it starts after 10 minutes — you can change this in the screensaver settings. Repeat steps 1–3 on each additional PC using the same license key.
Deploy to hundreds of machines without touching each one individually

The installer is free but requires a license key to activate. Pick a plan and your key will be emailed to you instantly after checkout.
