This issue is caused by duplicate versions of our software located within the Photoshop or Photoshop Elements Plug-in folder, specifically a duplicate instance of the "Selective Tool" folder. Please follow the steps below to resolve your issue.
1. Quit out of Photoshop.
2. Navigate to one of the following typical Photoshop or Photoshop Elements Plug-Ins folders:
- Windows - C:\Program Files\Adobe\Photoshop\Plug-ins or C:\Program Files (x86)\Adobe\Photoshop\Plug-ins
- Mac - Applications>Adobe Photoshop>Plug-ins
3. Look for the folder called Nik Collection. The file structure should look something like this (Mac and Windows):
- Analog Efex Pro 2
- Color Efex Pro 4
- Dfine 2
- HDR Efex Pro 2
- Selective Tool
- Sharpener Pro 3
- Silver Efex Pro 2
- Viveza 2
4. When you look at ‘Nik Collection,’ ensure there are no duplicate folders. For example, sometimes there is a ‘Nik Collection’ within the ‘Nik Collection’ folder. That is a sign something may be incorrect. Typically the second Nik Collection folder will have an additional ‘Selective Tool’ folder. There should only be one instance of each of the folders shown above which includes all subdirectories within the Photoshop Plug-ins folder as indicated in step 2.
5. Delete all duplicate folders including any additional Nik Collection folders after you have moved the contents to the main Nik Collection folder.
6. If you do not see duplicates directly in the Photoshop folder, then search on your system for a "Selective Tool" folder in other locations. Any other location other than the locations listed above will be incorrect installations, so the folders should be deleted.
