Symptoms

When you try to register a machine using the Power Automate machine runtime application, you receive the following error message:

An error occurred while registering your machine. Power Automate may have not been installed properly. Follow the steps in the learn more sections.

Cause

This issue occurs because the Power Automate for desktop application isn't properly installed due to a previous installation or uninstallation that puts the "NT Service\UIFlowService" user profile in a broken state.

Resolution

To solve this issue,

  1. Uninstall Power Automate for desktop from the machine and make sure the related files, located in C:\Program Files (x86)\Power Automate Desktop, are deleted.

  2. Reset the user profile manually.

    1. Verify the settings of the "UIFlowService" profile:

      Open the Registry Editor and go to the key folder:

      Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-80-3017052307-2994996872-1615411526-3164924635-3391446484

      If a second key exists with the .bak extension, you can delete it.

    2. Go to the location of ProfileImagePath.

    3. Verify that the UIFlowService folder is present in that directory. By default, it's located in %SystemRoot%\ServiceProfiles.

    4. Modify the ProfileImagePath value to point to the existing UIFlowService folder. By default, it should be %SystemRoot%\ServiceProfiles\UIFlowService.

  3. Restart your machine.

  4. Install Power Automate for desktop again.
