CCDciel can run on any current version of Windows. The oldest supported version is Windows 10.

The CCDciel installer is available in 32bit and 64bit. The 64bit version is recommended, install the 32bit version only if you need an old ASCOM driver that only work in 32bit.

To use the devices connected to your Windows computer you need the latest ASCOM platform and the most recent drivers for your hardware.

But you can also use the devices connected to a remote Alpaca, or a remote Linux system (a Raspberry PI for example) using the INDI protocol.

You can download the setup installer from the Sourceforge download link.

See also the list of the optional dependencies to install to take full advantage of the software.

A very important point when using Windows astronomy software is to
NEVER run anything as administrator
this is the source of many issue when accessing shared resources like a ASCOM driver. No current software need that despite the popularity of this false advice in astronomy forum.
