Use Help → Check for Updates. If the in-app download fails, use the latest installer from the download section. Installing it over the existing copy keeps the same application identity.
Enter the email used at Stripe checkout and the key shown on the purchase confirmation page. Check for copied spaces. If a machine slot must be released, use Help → Sign In & Activate License → Sign out of this installation on that machine.
Email support from the checkout address with the approximate purchase date. Do not send card details. Automated email recovery is not available yet, so recovery is handled manually.
Each subscription supports three active installations. A machine that does not validate for 30 days releases its slot automatically. If you still have the machine, signing out in the app releases it immediately.
The current early-access installer is not yet code-signed. Confirm the version and SHA-256 shown on the download page before running it. If the values do not match, delete the file and contact support.
