This is a windows file. Let me copy paste the information they provided here:
If this cannot be uninstalled via Settings - Apps, then please use Windows Install/Uninstall troubleshoother:
Please read the description and press ‘Download troubleshooter’ . When download is complete, open the file and follow the instructions:
- This app helps to get rid of problems which block standard installation and uninstallation processes. Click ’Next’ .
- Choose what you are having trouble with, in our case – ’Uninstalling’ .
- Find the program you want to delete. Please find ‘NikCollection’ among the suggested ones and click ’Next’ .
- Confirm that troubleshooter can delete the app. Click ‘Yes, try uninstall’ .
- In the next window you should see that troubleshooter has found the problem and fixed it. You can click ‘Close the troubleshooter’ .
This is how i was able to do it.
