Windows Update Issue

IRIS PAYE-Master Database Upgrade Tool

In order to correct the issues accessing data files caused by the recent Windows updates, we have developed a utility which will allow PAYE-Master users to use the software normally without having to remove the offending Windows update(s).

Please follow these steps to upgrade your PAYE-Master data file to restore normal usage.

1. Download the utility. Click here to download.
2. At the end of the install wizard, tick the option to launch the utility and click "Finish"

3. The utility will start, click "Upgrade All"

4. The utility will read Central.DAT for company data affected by this issue. Once the list is populated click "Upgrade Listed Companies".
Please note: screenshot below is empty as no affected data files found on this installation.

5. The utility will run through and correct the affected data files and will prompt when complete.

6. Log in and run PAYE-Master as normal.

If you encounter any errors using the utility or are still unable to use PAYE-Master after completing the process, please contact our support team at for further assistance.
