Download
StarTools is a 64-bit optimized application for multi-core processors, with at least 6GB of memory available. For larger datasets 16GB to 32GB may be required. Fast SSD access will greatly benefit the application. Always check for oversampling and Bin down your dataset to a lower resolution where possible. Legacy 32-bit machines and operating systems are also still supported.
The single ZIP archive contains the executables for Windows, macOS and Linux. StarTools is a pure native application and does not rely on other frameworks.
Never download StarTools from anywhere else but startools.org. We do not allow distribution of StarTools by any other party, on-line or off-line. If you find a copy of StarTools not hosted on startools.org, please let us know.
macOS notes
Some macOS (e.g. Sierra and above) users may need to run;
xattr -dr com.apple.quarantine StarTools.app
to un-quarantine StarTools.
This command needs to be run from the folder where the StarTools application is located (you can use the 'cd' command to navigate to the right folder, while using the TAB key to auto-complete the path).
Alternatively StarTools can be launched via control + click on the application, Show Package Contents, navigating to Contents/MacOS and clicking on the application.
Apple has been making it increasingly difficult for independent developers to distribute applications. As of Sierra you will need to follow the following steps to run StarTools.

Download manual
StarTools uses AIFE.AI for content management and digital footprint. This means that the website content doubles as a printable manual and vice-versa. This content is also available as a smartphone/tablet app, virtual flipbook, virtual reality (VR) experience and more.
StarTools is display-device agnostic, but can be configured to display its GUI at a 4x higher resolution to accommodate high-DPI devices and 4K displays.
Some less reputable virus scanners such as BitDefender, Norton and SpyBot may falsely report StarTools as a Trojan or Potentially Unwanted Program (due to malware that carries a similar name). Despite multiple users going through the lengths of getting StarTools white listed, the same problem pops up every 6 months or so.
The minimum specifications for a computer to run StarTools successfully depends mostly on the resolution the data you intend to process.
As of 1.3.180 Beta, StarTools uses all cores that it can find to speed up your processing in situations where it makes sense.
The 32-bit version is meant for older computers with less memory and/or a 32-bit Operating System.
StarTools is a completely native, self-contained application that does not require any further installation of helper libraries or run-time frameworks.
If you had bothered to read the 'buy' page, you would have learned that you could spare yourself the effort of writing a keygen or crack - if you can't afford the license fee and you are a genuine enthusiast, we're happy to work something out!
