IRIS Keytime System Requirements

Before installing the latest version of the Keytime Accountants’ Suite software, please ensure that the systems you are using meet or exceed the minimum platform, hardware and software requirements; including service packs, detailed below.

Microsoft products – end of life

Microsoft has announced that the following product has gone out of extended support:

  • Windows Server 2023/2012 R2 – 10/10/2023

This means that while you IRIS product may continue to work using the above versions, IRIS will no longer test in these environments and will not be able to offer support to customers using them, Remember that being on an older version of any software means that you are not getting the latest security updates. We advise that you are always on the latest versions.

What you need to do next

Our recommendation is to move to a later version of the Microsoft software:

  • Windows Server 2016, 2019 or 2022

Note: Windows Server 2016 is in Extended Support. This means that while security updates will be applied, other updates may not.


Hardware requirements

So that you get the most out of your software your computer must be capable of running the software effectively. The following guide gives you the information you need to check that your software will work properly on your hardware.

As well as the minimum requirements we also provide a recommended specification.  Whilst the software will run on the minimum supported hardware, we strongly recommend that you upgrade to at least the recommended configuration as soon as possible.

Supported Platforms

Microsoft extended support

When a supported platform is in ‘Extended Support‘, your IRIS product may continue to work but our teams will no longer test using these platforms and will be unable to offer support to customers using them. We advise that you upgrade to a later version.

HMRC mandated updates

HRMC are currently updating their authentication process to increase security. If you are still using Windows Server 2012/2012 R2, your ability to retrieve client information direct from HMRC will be impacted. Please ensure you upgrade to a supported platform (Microsoft Server 2016, 2019 or 2022).
