XRL Error 372 and Run-time Error 429

There are two commonly reported errors relating to the use of XRL as a result of the Microsoft Windows Update KB4011051

  • Error 372 Failed to load control 'SSTab' from tabctl32.ocx
  • Run-time Error 429 You do not have appropriate licence to use this functionality

 The recent Microsoft Windows Update KB4011051 has been reported to Microsoft so that they can address the issues that have been caused by it.


Work Around:

Disable updates in MS Office and use MS Office with a build of 16.0.8229.2073. To achieve this, follow the steps below: -

  1. Open an Excel spreadsheet and navigate to File>Account>Office Updates>Update Option and select ‘Disable Updates’.
  2. Close Excel and any other MS Office applications.
  3. With Administrator permissions, Open the Command window.
  4. In the Command window, run the command;

    CD “C:\Program Files\Common Files\Microsoft Shared\ClickToRun” 

  5. Then run the command;

 OfficeC2RClient.exe /update user updatetoversion=16.0.8229.2073

Note: the commands, in points 4 and 5 above, must be typed exactly as stated, paying particular attention to spaces and quotes.

This process will trigger Microsoft to download and update your current build and normally takes a few minutes. Once completed, check the build version by opening an Excel spreadsheet and navigating to File>Account>About Excel.
