On which Operating Systems Does the World Clock Work?

Anuko World Clock works on the following Windows operating systems. Mac users: see this note.

World Clock version 6.0 and above: 64-bit Windows 7, Windows 8, and Windows 10 (prior to build #14291, see note below, being below build #14291 means that Windows 10 Anniversary Edition, known as version 1607 is not fully supported, as well as everything after it). Not full support means that taskbar replacement mechanism that the World Clock uses to display itself in the system taskbar is no longer available in the operating system. You can still run the clocks on desktop. If you have negotiation power or other leverage, you may wish to ask Microsoft why this feature is removed from the OS. We tried and failed to convince them that it was an evil thing to do. Well then, at least you still have a choice of not using Windows 10.

Versions prior to 6.0
  • Windows XP, Vista, Windows 7, Windows 8, and Windows 10 (prior to build # 14291, see note below).
  • Servers: Windows Server 2003, 2008, and 2012.
For World Clock up to, but not including version 6.0, both 32 bit and 64 bit versions of the above mentioned operating systems are supported. One installer should work on either 32 bit or 64 bit OS. In other words, you don't need a platform-specific installer. With version 6.0 things have changed, as support for old 32 bit operating systems was dropped.

Note for Windows 10 builds 14291 and above, including Anniversary Update version 1607

World Clock will not work in taskbar in such builds, because the mechanism to draw a custom clock window is no longer supported by the operating system. Use desktop clocks instead. In other words, taskbar clock replacement feature is the only feature that is broken in such builds.

See some example screenshots below.

For best results on Windows 10 use World Clock version 5.8.1.4697 or above. Build 4697 addresses the font visibility issue in Classic or Standard System Clock skins (an issue specific to Windows 10).

Note: some older video adapters may not support OpenGL mode, which is required for interaction with the world map that is used to see the world time. Check this for more details. If you run Anuko World Clock on Windows Vista or Windows 7 it is critical that you have installed a proper, most recent driver for your video adapter.
