To provide you a great user experience Exact products use the newest technologies. To support these new technologies the system requirements are revised regularly when releasing a new product update. This is also the case for product update 409 and 254. As of product update 409 and 254 the system requirements will change. For instance, the installation of Microsoft .Net Framework 4.5 will be a requirement.
Because Microsoft .Net Framework 4.5 is not supported for Windows Server 2003, and because according the Microsoft support lifecycle policy the support for Windows Server 2003 will stop as of July 2015, we are unfortunately forced to stop the support for Windows Server 2003 as of product update 409/254.
If you are using Windows Server 2003 and want to update to product update 409/254, we advise to timely upgrade to a newer supported operating system.
