How to Reinstall Adobe Acrobat Pro 2017 with a Registered Serial Number
Question details
The user needs to reinstall Adobe Acrobat Pro 2017 but is unable to proceed because the system reports that the product's serial number is already registered.

- Product
- Adobe Acrobat Pro 2017
- Device & OS
- not provided
- Scenario
- Attempting to reinstall a previously purchased perpetual license of Adobe Acrobat.
- Observed behavior
- The installer or registration portal rejects the serial number, displaying an error that the product code is already in use by an account.
Ensure you have access to the email address and password for the Adobe account you originally used to register your Acrobat Pro 2017 purchase.
Download Directly from Your Registered Adobe Account
Since perpetual licenses are registered only once, you can bypass the serial number prompt by redownloading the software directly from your linked account.
Adobe requires perpetual licenses to be registered a single time. Re-entering the serial number on a new installation triggers an 'already in use' error.
Navigate to the official Adobe 'Download Pro or Standard versions of Acrobat DC | Non-subscription' page.
Click 'Sign In' and enter the exact Adobe ID (email address) that you used when you first purchased or registered Acrobat Pro 2017.
Go to your account's registered products or order history to find Acrobat Pro 2017.
Click the download link corresponding to your operating system and run the installer. The software will authenticate via your account rather than requiring the serial number again.

Contact Adobe Support with Proof of Purchase
If Acrobat Pro 2017 does not appear in your account, you may need Adobe's help to link the license properly.

Frequently Asked Questions
Why does Adobe say my Acrobat serial number is already in use?
Adobe perpetual licenses only need to be registered once. If you attempt to enter the serial number again during a reinstallation on a new device or after resetting your PC, the system flags it as already claimed by your Adobe account.
Can I transfer my Acrobat 2017 license to a new computer?
Yes, you can transfer your license. You must first deactivate the software on your old computer by opening Acrobat and selecting Help > Sign Out. Then, install it on the new computer and sign in with your Adobe ID.
Where can I find the download link for non-subscription Acrobat versions?
You can find the official installers on Adobe's 'Download Pro or Standard versions of Acrobat DC | Non-subscription' page, which is accessible through the Adobe Help Center.
