  I've had better success by doing the following:

  From an elevated command prompt, run:

  wmic product where 'name like 'labtech%%' call uninstall /nointeractive

  sc delete ltservice
  sc delete ltsvcmon
  Sc stop ltservice
  sc stop ltsvcmon

  Then remove the following registry keys and all sub-keys/values:

  HKLMSOFTWARELabtech
  HKLMSOFTWAREWow6432NodeLabtech

  We had ConnectWise installed on our systems previously, which is a LabTech application. It installed a program called 'ScreenConnect Client' with a random series of numbers and letters after. We had to use this batch file to remove it.

  @echo off
  wmic product where 'name like 'ScreenConnect Client%%' call uninstall /nointeractive
  sc config ltsvcmon start= disabled
  sc config ltservice start= disabled
  sc config labvnc start= disabled
  sc stop ltsvcmon
  sc stop ltservice
  sc stop labvnc
  taskkill /IM LTTray.exe >nul
  sc delete ltsvcmon
  sc delete ltservice
  sc delete labvnc
  reg delete 'HKLMSOFTWARELabTech' /f
  reg delete 'HKLMSOFTWAREWow6432NodeLabTech' /f
  rmdir /s /q C:WindowsLTSvc

  There may also be some residual files in the Windows Temp folder as well that you may want to delete or clear.
