Microsoft 'End of Support' Dates

When Microsoft products reach their 'End of Support' dates, they are no longer supported and do not receive security updates. It is therefore recommended that you upgrade to later products before these dates.



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.

How to Install
  1. Create New Folder
    Create a new folder on your File Server. For example, "Z:\My VAT Returns" or '\\MyServer\My VAT Returns\'.

    Tip: You may wish to create a shortcut on your Windows Desktop, which points to this folder. Note: The actual file name of the software will change when subsequent versions are released, so the shortcut needs to point to the Folder and not the file.

  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 Manager to function correctly, a few changes are required within the Excel Options.

      (For example, "Z:\My VAT Returns"). 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.

Files created by this product are organised using a preset folder structure. Sub folders are created automatically within the folder where the workbook is located. It is recommended that the VAT Return workbook is stored in a specific folder. For example, "C:\My MTD VAT Returns".

Archive Folder: The sub folder "\Archive" is automatically created when you first use the software. After you have updated to a new version, this may be a convenient location to store your previous version. This may avoid confusion as to which is your latest version.

Receipt Files: When a draft or finalised VAT Return is saved as a PDF file it is stored, by default, to the sub folder "\Receipts". However, For each Taxpayer, the folder location can be changed, essentially allowing you to store the PDF receipts in any accessible location. Once changed, the new folder location becomes the default for that Taxpayer.

Evidence Files: During each VAT Return submission, copies of the full submission and HMRC response are saved to the sub folder "\Evidence". These files are stored in Text and JSON format and can be viewed using a 'Text' editor such as NotePad or WordPad.

Data Backup Folder: Each backup created by the 'Backup Data' routine is stored in the sub folder "\Backup".

Import Folder: When you Import a VAT Return from, for example an Excel workbook, the routine first searches in the sub folder 'Import'. This may be a convenient location to store the files. However, For each Taxpayer, the file folder location is saved automatically after each import, therefore you can essentially store the files in any accessible location. This folder location then becomes the default for future imports.

Bin Folder: The sub folder "\Bin" is used to store technical log files created by the software. These log files may assist in the resolution of technical issues that may occur during the use of the software.
