after insalatoin it says newer version already installed when in fact its not true

Hi @moses25724514rrm3,

I hope you are doing well. Sorry for the trouble and delayed response.

Since it shows already installed, try the below steps:

1. Restart the computer;

2. Please run the Acrobat cleaner tool https://www.adobe.com/devnet-docs/acrobatetk/tools/Labs/cleaner.html. To remove any traces of the previously installed version;

3. Download the offline installer from here: Adobe - Adobe Acrobat Reader DC Download | Free PDF viewer for Windows, Mac OS, Android

4. Once downloaded, try to install the newly-downloaded file.

I hope this helps.
