Microsoft has today ended its support for the Windows NT operating system.
We must also announce that PC-Topp.NET is not supported any more under Windows NT. That is so because many of Microsoft's system components that PC-Topp needs to function don't work under that legacy operating system. PC-Topp.NET clients are supported exclusively under Windows XP Professional and under Windows 2000. Support under future versions of Windows will be announced as soon as any adaptations that may be required have been implemented.
If your system still runs under Windows NT, then you should strongly consider upgrading to new hardware and an up-to-date operating system. New hardware will most likely be necessary as it is likely that your PC is many years old, and cannot show the complex PC-Topp.NET web pages with adequate speed.
