License Deactivation
Symptom: Capture One opens in trial mode, shows a license error, or refuses to launch with a subscription message. Root Cause: Capture One license deactivated because the subscription lapsed, the offline grace period expired, or macOS hardware ID changed. Referred from: DIT Triage - C1 Crashed, DIT Triage - Tether Dead
Diagnosis
-
Launch Capture One. If it shows:
- “Trial Mode” or limited features — subscription has lapsed or was never activated
- “License expired” or “Subscription ended” — payment failed or subscription was cancelled
- “Activation limit reached” — too many machines activated on this license
- “Offline grace period expired” — the license requires periodic online validation and the grace period (typically 30 days) has passed
-
Check internet connectivity. If the laptop has internet access, Capture One may re-validate automatically.
Fix
If internet is available
- Capture One menu > License > Sign In (or Activate)
- Enter the photographer’s Capture One account credentials
- If the subscription is active, the license should validate immediately
- If “Activation limit reached”: the photographer needs to deactivate another machine from their Capture One account (account.captureone.com) or contact support
If internet is NOT available
- You’re within the offline grace period (30 days from last online validation) — Capture One should still work. If it doesn’t, the grace period has expired.
- Grace period expired — You need internet. Options:
- Connect the laptop to the venue’s Wi-Fi temporarily (just for license validation — doesn’t need to be the DIT network)
- Tether the laptop to a phone hotspot for 60 seconds (just long enough to validate)
- If no internet at all — Capture One will not run in full mode. Fallback options:
- Use Capture One in trial mode (limited features, may still tether)
- Use an alternative tethering solution if available
- See EC - Card Import Fallback as last resort
If the subscription actually lapsed (payment failed)
- This cannot be fixed on set. The photographer needs to renew their subscription.
- If the photographer has an old perpetual license: they can switch to that version (if still installed)
- Temporary: some Capture One versions allow limited trial use — enough to tether for the day
Prevention
- Verify the license before shoot day. Open Capture One and confirm it’s not in trial mode.
- Ensure the laptop connects to internet at least once every 2 weeks to keep the offline grace period refreshed.
- Keep subscription payment details current. Set up auto-renewal.
- Have the Capture One account login credentials available (email + password) in case re-authentication is needed on set.
