The Robot service does not come with an uninstaller, so removing it from a server requires use of command line tools.  This is made more complicated by the fact that for a while the App Manager installed the Robot with a standard display name ("Pentana Robot Service"), so the first task is to identify the correct instance.

Run the following PowerShell:

Get-WmiObject win32_service | ?{$_.Name -like '*Pentana*'} | select Name, DisplayName, State, PathName

This will show the name of the service (not just the display name), plus the path to its folder.

Now you can:

• Ensure the service is stopped
• Delete the program folder
• Delete the service - if you are still in the PowerShell window use the command:
  

  &sc.exe delete <name of service>  # e.g. &sc.exe delete ServerRobotPentanaUAT

   

If you are removing the Robot but it's partner application service will remain, consider:

• The MSMQ:  jobs should be processed prior to removal
• The application service should have the MSMQ commented out so that it does not continue to add messages that will not be processed
