Error 40: Failed to download

When checking for updates in TurboTax, you may receive the error message Failed to download Error 40. The Further details section in the error window will contain another message, like:

  • The operation timed out
  • A connection with the server could not be established
  • The server did not return the file size. The URL might point to dynamic...
  • The server returned an invalid or unrecognized response
  • The server name or address could not be resolved
  • The connection with the server was terminated abnormally
  • There are currently no active network connections...
  • An internal error occurred in the Microsoft Windows HTTP Services

The message may also contain a very long web address similar to this shortened example: http://download.esd.intuit.com/ESD/Files/CTG/comp/...msp

Error 40 is a generic download error that has several potential causes, including, but not limited to:

  • A slow internet connection (like dial-up)
  • Interference from a firewall or web accelerator program
  • A malfunctioning Windows component Background Intelligent Transfer Service (BITS)

Solutions

  • If you receive Error 40 while updating through TurboTax, download and install a manual update instead.
  • Disable your web accelerator program if you have one. Web accelerators (also called dial-up or download accelerators) are programs that speed up the downloading of large files and are mostly used by dial-up customers.
  • Configure your firewall to work with TurboTax or temporarily disable your firewall software before downloading your update or state program. Remember to turn your firewall back on when you're finished.
