C:\ProgramData\Blackmagic Design\DaVinci Resolve\ (Note: ProgramData is a hidden folder. Enable "Hidden items" in File Explorer View settings to see it).

The software lacks the write privileges required to save the license file to your system drive.

If the software cannot write to protected system folders, it will lose activation every time.

Third-party cleaning software or antivirus programs are deleting the license file, viewing it as a "temporary" file.

Using VPNs or virtual network adapters can confuse the hardware ID verification.

The activation prompt can appear for several reasons. Understanding the core causes is the first step toward a resolution:

Remember: The free version's pop-up is not an error—it's an advertisement. The Studio version's repeated requests are a bug that Blackmagic has slowly improved with each release (versions 18.6 and 19 have far fewer activation issues).

If you are using the (download from the website without a key) and it asks for activation, you have accidentally installed the Studio version . The free version never asks for a key.

: A stable internet connection is required for the initial handshake. Temporarily disable firewalls or VPNs during activation, as they can block the verification process.

If you have "forced" deactivations too many times in a short period—by repeatedly entering the key on different machines to bump off old ones—you might trigger an anti-piracy lockout.

Several factors can trigger this issue, ranging from operating system updates to network configurations.
