Error 0x800401F0 occurs on Windows PC when programs or drivers for hardware are installed. The most common error occurs when devices are connected over a network or connected to a remote desktop. The reason is that there are not enough rights to change the software or access a network resource.

This is because Windows Installer is unable to connect to the installer server. You can try uninstalling Windows Installer and re-registering.

Unregistering / Unregistering Windows Installer

Unregister Windows Installer and re-enter Windows Installer. To do this, proceed as follows:

  • From the Start menu, click Run.
  • In the Open box, type msiexec / unreg and press Enter.
  • From the Start Menu, select Run.
  • In the Open box, type msiexec / regserver and press Enter.

Run Windows Update Troubleshooter

Windows 10 includes bug fixes that can automatically detect and fix issues with updates and patches. If the problem is not obvious and you are unsure of what to do next, try this troubleshooter. A solution may not always be found, but this is a great place to start.

Step 1. Go to the search box and type Troubleshoot. Select the Expected Debug Options option in System Preferences.

Step 2. A new troubleshooting window will open. In the first section titled Get Up and Run, you should see an option for Windows Update. Choose this.

Step 3. You should now see a new button that says Run Troubleshoot. Select it to start troubleshooting and see how it can help you automatically.

Step 4. A new troubleshooter window will open while Windows 10 looks for problems. When it detects problems and checks for everything from missing updates to corrupted files, it notifies you and asks if you want to apply this fix or ignore this fix. Since you are trying to restore an update, we recommend that you always select the Apply option here.

When you’re done, the troubleshooter will provide you with a list of all the issues it found and fixed. At this point, you can choose Close to exit. If the troubleshooter finds and fixes important issues, try updating again.
