Important Note for Excel 2007, 2010 & 2013 users

Early releases of Excel 2007, 2010 & 2013 contained serious errors and security issues. Some of these errors may not be encountered during normal use. However, the bridging software uses certain advanced features of Excel, which will trigger these errors. Consequently, all 'Important' Windows & Microsoft updates should be installed as described above.

Important Note for DropBox users

How to install the Compatibility Checker
  1. Create New Folder
    Create a new folder on your computer. For example, "C:\My Checker".

  2. Change Excel Configuration (Options/Trust Centre)
    Microsoft has taken a much tighter approach to software security. As a result of this, some Excel features are disabled during initial installation. In order for the VAT Return Demo to function correctly, a few changes are required within the Excel Options.
    Open a blank workbook in Excel. (For recent versions of Excel, Click on 'File' menu, then 'Options', then 'Trust Centre' then click on 'Trust Centre Settings').
    Note: For Office 2007, Click on the 'Office' button as the 'File' menu does not exist.
    1. Trusted Locations: Add the 'Location' of the folder where you saved the workbook,
      (For example, "C:\My Checker"). Also tick the box 'Subfolders'.
    2. Macro Settings: Tick the box 'Trust Access to the VBA project model'.
    3. Then, click on the 'OK' button.
    4. Finally, Exit Excel.

  3. Download Software to Folder
    Download the 'NJT Compatibility Checker', then (move or save) it to the folder you have just created.

    Click on the button to download the free Compatibility Checker.

    Note 1: The download process may vary depending upon which Internet browser you use and the browser's configuration.
    Note 2: It is important that you store the software within it's own folder as certain sub folders are automatically created when the software is opened.
