Ononecorefoundation.dll Is Missing From Your Computer- Photoshop Error Message

This error message is isolated to the Windows OS. There are two possible causes and solutions for this problem below. In most cases, this error will occur if there are older plugins lingering in your plugins folder of Photoshop caused by copying or moving contents within the Adobe Photoshop plugins folder across different versions.

Please note, you will never need copy or migrate any plugin files for our programs manually. The installer will automatically install all necessary components for all compatible host applications on your machine. Moving plugin files in your Adobe Photoshop plugins folder likely cause problems with your ON1 or other Photoshop plugins.

 

How to fix the ".dll is missing" error:

If you are running Adobe Photoshop Cs6, go to the Adobe Photoshop plugins folder and delete any old or lingering ON1 plugin files. Here is the path to the Photoshop Cs6 Plugins folder:

C:\Program Files(x86)\Adobe\Adobe Photoshop CS6\Plug-ins

 

For all versions of Adobe Photoshop CC, Adobe has moved to a shared plugins folder. Shared Creative Cloud Location - which will load the plug-in for all installed versions of Photoshop CC (Photoshop CC & Photoshop CC 2014 & Photoshop CC 2015 & Photoshop CC 2015.5 & future versions of Photoshop CC when they are released, like CC 2017) without having to reinstall the plug-in. If you are running a CC version and receiving the ".dll is missing error" on startup, please delete all old ON1 plugin files from this folder:

C:\Program Files\Common Files\Adobe\Plug-Ins\CC

Delete any older ON1 plugin files of ours that may still be lingering in the plugins folder or a subfolder in the plugins folder.

 

 

Why am I still receiving the ".dll is missing" error after removing the older On1 plugin files?

Another possibility for the error is if you are running Photoshop Cs6 and have enabled the option to use an additional Plugins folder. This is a preference set in your Photoshop Preferences > Plugins.

Uncheck the Use Additional Plugins folder, then quit and restart Photoshop.
