Uninstall Troubleshooter - Need 38 Character Product Code

For Windows 11
I need to reinstall NIK5. The install program says NIK5 is already installed and NIK is on my Apps list. Uninstall from the Apps list does not work. I receive a Status Code of 0x80070643.
When I run Windows Program Install and Uninstall troubleshooter Nik or DxO does not appear on the list of programs. When I click “Not Listed” the troubleshooter asks for the 38 character product code.
What is the code? Thank you.
