How do I resolve a QBXML error when installing AvaTax for Quickbooks?

Overview

During installation of AvaTax for QuickBooks or while manually running the Subscribe.exe utility, an error message appears:

"HRESULT = -2147220445 (80040423) The version of QBXML that was requested is not supported or unknown."  (version numbers vary)

or

"Error while Subscribing to Quickbooks Events. 
Function Name = DoSubscribeEvents 
80040423 
The version of QBXML that was requested is not supported or is unknown. 

Please login Using Administrator Privileges and try again." 

Environment

QuickBooks

Resolution

  • The most common reason is inadequate permissions on the Avalara folder (and subfolders) typically found in the Program Files or Program Files (x86), right click the Avalara folder > left click Properties > click Security Advanced 
    • In the window, choose Users > click Change Permissions highlight users > click Edit > click Full Control "Allow" check box > Ok all the way back until you have closed the original.
    • If you get any messages that you do not have permission to do this, you will need to have a network administrator or someone with higher permissions to your workstation complete this.
  • Next use Windows Search to find cmd.exe, then right-click and choose Run as Administrator
    • Type 'cd Program files(x86)/Avalara/AvaTax Adapter/Bin' without the quotes.
    • Type Unsubscribe.exe and press enter. Wait for the message to continue and press enter again.
    • Type unregister_for_callback and press enter. Wait for the message to continue and press enter again.
    • Type unregister_for_Adapter and press enter. Wait for the message to continue and press enter again.
    • Type register_for_Adapter and press enter. Wait for the message to continue and press enter again.
    • Type register_for_callback and press enter. Wait for the message to continue and press enter again.
    • Type Subscribe.exe and press enter.
  • If all is correct there will be no error message.
  • Start QuickBooks (by right clicking the icon on the desktop or on the program in your start menu) and continue with the installation. 

 

Note: If updating folder permission does not allow Subscribe.exe to complete, the newest version of QBFC must be installed, and then installation of the Avalara software can be completed. Please submit a case to Support.
