A: Yes. Version 4.1.0.12 is fully free (freemium). The "Pro" features (like removing the watermark and adding more layers) required a one-time license key, but today those keys are no longer sold. The free version gives you up to 3 layers and a small watermark. For personal use, this is often enough.
Since the official ManyCam website typically offers only the latest version, you will need to use a reputable . manycam 4.1.0.12 download for pc
