If activation does not finish

The purchase remains safe. These quick checks solve the most common handoff and restore issues.

The app did not open

Install or update to Display Dimmer 2.2.8 or newer. Return to the purchase confirmation if it is still open, or use the receipt key with the manual direct-purchase path above.

The key or email is missing

Check spam and the email address used at checkout. Your receipt contains the key needed for manual activation. If it is still missing, contact support.

The activation limit was reached

Reinstalling can use another activation. Send the order email and a short explanation to support so the license can be reviewed safely.

Microsoft Store cannot find Pro

Confirm Microsoft Store is using the purchasing account, restart the Store and Display Dimmer, then use Restore from Microsoft Store again.
