During installation I get an error message 0x80070643

This information applies to all versions

Usually, this problem is not related to Nik Collection, but to corrupted files in the Windows System (or lack of the necessary system updates). There are some possible ways to resolve the issue with the error message 0x80070643.

A.

First of all, make sure that your system is up to date and all recommended updates are installed. Please check that the .NET Framework is not corrupted using Microsoft .NET Framework Repair Tool from the official Microsoft page.

Download the file and run it as a usual installation file.  During installation, I get an error message 0x80070643

System requirements don't mention Windows 10/11, but the tool was maintained until 2019 and seems to be working with Windows 10 as well.

B.

Another option is to check for corrupted files with Command Prompt:

1. Open Windows Searchbox and type cmd, you should see the Command Prompt app.
2. Right-click on the app to open the sub-menu, here you need to select 'Run as Administrator'.
3. In the opened window type in the following command: sfc /scannow.
4. Press Enter to run the command and wait until it is finished.
5. You should see a message like 'Windows Resource Protection found corrupt files and successfully repaired them...'

Also please try to delete Nik Collection using Windows Install and Uninstall troubleshooter:

1. Download the troubleshooter from the official Microsoft page.
