Unable to uninstall Adobe Photoshop Elements 14 from my Mac mini running macOS Sequoia

To uninstall an older version of Adobe (PSE 14 is from around 2015?), there are "manual" steps required. The uninstaller app is an old 32bit application that can't run on a modern macOS anymore.

Follow these steps:

1. Quit any running Adobe processes. You can do that by opening "Activity Monitor from Applications > Utilities. Then search for Adobe in the search bar. If you see any processes with Adobe in them, select them and click the X button to force quit them.
2. Remove the actual Adobe applications. Open Finder and go to /Applications. Locate the Adobe folder and drag it into the Trash
3. Delete any leftover files, since you're not able to run the uninstaller app. Those leftover files are located here:

• Go to Finder and check ~/Library/Preferences folder. Look for "com.adobe.PhotoShopElements14.plist" or similar. Drag them to the trash
• Go to ~/Library/Application Support/Adobe. Find and delete Photoshop Elements folder or PSE 14 folder (or similar, if present)
• Go to ~/Library/Caches. Search for folders like com.adobe.PhotoShopElements14 or any other Adobe-related catches and remove them by dragging them to the trash.

After this, Empty the Trash, and Restart your computer. This should clear out any other lingering system references.
