Activate ShrinkCut
Open ShrinkCut on Windows and enter the email and license key from your purchase email. The app validates online against shrinkcut.uk.

If validation fails
- Confirm you are not using a revoked or refunded key.
- Check machine limit (default two devices).
- Contact support with your order email.
Trial installs allow 3 jobs, then require activation. Offline use works with a cached signed license within a 14-day grace window after the last online check.
