Are you prompted to enter a serial number or sign in with your Adobe ID when you start Acrobat Pro or Acrobat Standard? There are several reasons why you may be getting this prompt:
- You may have installed the wrong version of Acrobat.
- There could be incorrect or missing information in your Acrobat subscription account.
- Your computer may be unable to reach Adobe's activation servers.
The method used to purchase your product determines your launch experience:
- Classic customers should be prompted for a serial number at the time of installation or launch of the product. Previously referred to as perpetual.
- Continuous customers should be prompted to Sign In during the launch process. Previously referred to as subscription.
The Acrobat continuous and classic versions each use a different installer. If you have installed the wrong version, it's necessary to uninstall the incorrect version before installing the correct version of Acrobat. If you receive a serial number prompt or sign in unexpectedly on launch, you must follow this process to install the correct version of the software.
Important: The trial version uses the classic installer. Continuous customers must uninstall the trial version and reinstall using the subscription installer.
