Installer for Photoshop Elements 14

You could try downloading the installer files from Prodesigntools which has been a reliable resource for Adobe download links for many years. I just tried and they downloaded fine.

https://prodesigntools.com/photoshop-elements-14-direct-download-links-premiere.html

You must follow the Very Important Instructions on that page first BEFORE you click the download links. otherwise you'll get an "Access Denied" error.

For Windows, you download both File 1 (.exe file) and File 2 (.7z file) to your local hard drive then double click the .exe file and follow the prompts.

Unfortunately, you won't find an installation file from Adobe.  Do you still have the installation disc or installation file?
