Adobe Acrobat Standard 2017 Activation Issue After Hard Drive Replacement

Hello Community,

 

I am currently using Adobe Acrobat Standard 2017. My old computer's hard drive was about to fail, so I followed the official instructions to sign out from my Adobe account on that device.

 

After replacing the hard drive and reinstalling Adobe Acrobat Standard 2017, I encountered an error message saying that my serial number is already in use on another computer. However, I have only ever used this serial number on this computer and no other devices.

 

I need assistance to resolve this activation issue and regain access to my product.

Hi @it_4299,

 

Hope you are doing well. Sorry for the trouble. 

 

Would you mind logging in to https://adobe.ly/4h0wxBl and scroll down to "Active Sessions," and clear all the devices that are listed there.

 

Once done, go to https://adobe.ly/4gSI3yx and check if the product is registered there.

Now try installing the app and check again.

 

Hope this helps.

I had the same problem - cleared all active sessions - product is registered there.

Tried to activate with my serial number which worked previously and is listed online.

Error message appears “we are unable to validate this serial number for Adobe Acrobat. Please contact Customer Support”

Tried that and support person says:

I understand. The only way forward is to raise this through community forum link. They can validate your serial number and reset the activation count for you, allowing you to reinstall and use the product on your current machine.

So here I am… Can someone here help?

I need assistance to resolve this activation issue and regain access to my product.

Hello ​@Robert_s 

 

I hope you are doing well, and thank you for reaching out to us. We are sorry for the trouble you had.

 

Please note that Adobe Acrobat 2017 Classic and Acrobat Reader 2017 Classic are now end-of-support products, whose support ended on June 06, 2022. To learn more, see this article: https://helpx.adobe.com/acrobat/kb/end-of-support-acrobat-2017-reader-2017.html

 

Also, Activation reset or serial validation cannot be done via the community forum/platform. Could you please share the support case number with us in a direct/private message so that we can check the details internally? To send a direct message, click on my user profile name and select message. Please include the community thread URL in the message.

 

Adobe strongly recommends that you update to the latest versions of Adobe Acrobat and Acrobat Reader. By updating installations to the latest versions, you benefit from the latest functional enhancements and improved security measures.

 

Suggestions:

  • Use the Acrobat Cleaner tool to remove the installed app.
  • Restart the machine.
  • Download the setup from your Adobe account.
  • Use the serial number for activation.

 

Please note that these steps may or may not work for an EOL product.

Regards,

Anand Sri.
