OPERATING SYSTEM:

Skyline is currently developed for Windows 10 and later.

Skyline is tested nightly on 64-bit Windows 10 and Windows 11.

Skyline was tested nightly on 64-bit Windows 7 until 2/23/2024 when use was below 2%.

Skyline 23.1 is the last major version to support Windows 7.

Skyline discontinued releasing 32-bit builds in 2021 after use fell below 1%. You can still download and install older builds.

Skyline 2.6 was the last version to support Windows XP.

-> All versions of Skyline since 1.4 can be downloaded from "Unplugged" installation pages by clicking "I Agree" and then the "Archive" link.

PROCESSOR, MEMORY AND DISK:

There is no minimum requirement, but for performance reasons a large fast hard drive is desirable.  The amount of memory needed depends on the size of your experiments, but 4GB is a good start. Skyline is frequently taught on relatively average modern laptops. But, for larger-scale processing we recommend a more powerful desktop system with dual 24- or 27-inch monitors to take full advantage of Skyline display capabilities.

We recommend modern i7 quad-core processors, running at 3.5 to 4.0 Ghz work well, with 16 to 64 GB of RAM and a fast SSD (e.g. 500 GB) + a spinning HD with more room (e.g. 2 TB).

A modern option as of June 2021 of the type favored by Skyline developers can be found on Amazon:

Dell XPS 8940 Tower Desktop Computer - 10th Gen Intel Core i7-10700 8-Core up to 4.80 GHz CPU, 64GB DDR4 RAM, 2TB SSD + 4TB Hard Drive
