SmartScreen warning: the file isn't EV-signed, so Windows may show "unknown publisher". Click More info → Run anyway, or verify the SHA256 checksum on the release page.

Activate Pro (optional)

The free tier covers 3 bulk operations and 50 inline edits per calendar day. To remove the limits:

  1. Buy a Pro license — you'll receive a key like PRO-XXXX-XXXX-XXXX by email.
  2. In the BlockParam dialog, click the License button in the bottom bar (it shows your current tier).
  3. Paste the key & click Activate. Status flips to Pro, daily limits gone.

Multi-seat deployments share a single key file — see Licensing.

Trouble?

Add-in doesn't show up, trust prompt won't accept, or you need to wipe local state — see Troubleshooting. For bugs or feature requests, open an issue on GitHub or email support@lautimweb.de.
