Change the on-premises Service account

The Power Automate service (UIFlowService) communicates with Power Automate cloud services for machine registration and running desktop flows.

By default, it runs as a virtual account created by the Power Automate installer called NT SERVICE\UIFlowService.

Most on-premises environments don't require changing the default configuration. However, you may run into errors registering machines or running flows for the following reasons:

  • Your network doesn't allow requests made by the NT SERVICE\UIFlowService virtual account to reach Power Automate cloud services.
  • Your machine or group policy disallows the Log on as a service privilege for the NT SERVICE\UIFlowService account.

In either of these cases, you can ask your domain or network administrator to grant NT SERVICE\UIFlowService the appropriate privileges. Alternatively, you can replicate the following steps to change the account with which the Power Automate service runs:

  1. Launch the Machine runtime application and select the Troubleshoot tab.
  2. Select Change account.
  3. Select This account.
  4. Provide the new account, for example: DOMAIN\AlexJohnson.
  5. Provide the password of this account and select Configure.

Changing the service account can also be accomplished by using a command line tool that ships with Power Automate called "TroubleshootingTool.Console.exe". This tool is useful when scripting the upgrade of Power Automate to a more recent version, as upgrading will reset the UIFlowService to run against the default virtual account.

You can find TroubleshootingTool.Console.exe in the directory where you installed Power Automate, typically "%programfiles(x86)%\Power Automate Desktop". To change the service account, do the following:

  1. Open a command prompt as an administrator and navigate to the tool.
  2. Create a temporary file with the account password as the only content inside (e.g. temp.txt)
  3. Type the following: TroubleshootingTool.Console.exe ChangeUIFlowServiceAccount <accountname> < <pathToTemporaryFile>
  4. Delete the temporary file

Example:

TroubleshootingTool.Console.exe ChangeUIFlowServiceAccount mydomain\myuser < tempfilethatcontainspassword.txt

The tool also provides other functionality such as getting the name of the account that the service is currently running as, resetting it to run as the default virtual account, or simply restarting the service. For more information on all supported commands, simply run the TroubleshootingTool.Console.exe with no arguments.

Troubleshoot desktop flow runs

If your desktop flow run fails, go to Errors when running attended or unattended desktop flows and find mitigation steps for different error codes.

If you encounter errors related to the desktop flow run queue, go to Troubleshoot desktop flow run queue errors.

Collect machine logs

There are several logs you can collect for the machine’s configuration and service logs. To do so, select Exports logs link in the Troubleshoot tool.

Resolve Power Automate agent for virtual desktops issues

If you encounter errors while launching the Power Automate agent for virtual desktops, perform the following steps:

  1. Close the RDP or Citrix session.
  2. Ensure you've installed the correct version of Power Automate for desktop.
  3. Connect again to the RDP or Citrix virtual desktop.
  4. Restart the Power Automate agent for virtual desktops.

If the agent for virtual desktops can't communicate with Power Automate for desktop, the agent will be closed. If you're sure that a correct Power Automate for desktop version is installed, one that supports UI automation in virtual desktops, try the following remediation steps:

  1. Open PowerShell

  2. Navigate to the appropriate directory using the following command:

    cd "C:\Program Files (x86)\Power Automate Desktop\RDP\DVCPlugin\x64"

  3. Run the following two commands:

    regsvr32 /u .\Microsoft.Flow.RPA.Desktop.UIAutomation.RDP.DVC.Plugin.dll

    regsvr32  .\Microsoft.Flow.RPA.Desktop.UIAutomation.RDP.DVC.Plugin.dll
