If the Administration Server acts as a WSUS server, the “Windows Update Agent error 80240033 (License terms could not be downloaded)” error can occur for the following tasks: 

  • Find vulnerabilities and required updates
  • Install application updates and fix vulnerabilities


  1. Open the Windows Registry of the device that has Administration Server installed. 
    To do so, type regedit.exe in the Windows search bar and press Enter on the keyboard.
  2. Add a new KLWUS_TREAT_EULA_TEXT_ERROR_AS_EULA_EXIST=1 value for the DWORD key to the corresponding directory:
    • HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\Components\34\1093\\ServerFlags
      for 32-bit systems
    • HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KasperskyLab\Components\34\1093\\ServerFlags
      for 64-bit systems
  3. Download the klscflag.exe utility and run the command below as an administrator:
klscflag.exe -fset -pv klserver -n KLWUS_TREAT_EULA_TEXT_ERROR_AS_EULA_EXIST -t d -v 1
  1. Restart the device with the Administration Server.
  2. Run the Find vulnerabilities and required updates task or the Install required updates and fix vulnerabilities task.
    The error will still persist after the task finishes, but the updates will be installed successfully.
