ATM is written in Java and can only be installed and run if the correct Java version is installed on the computer. Java can be found at Oracle and BellSoft:

Select the required Java version
Select the appropriate platform
Select the appropriate processor: an Intel X64 processor or an ARM64 processor

Below are the most commonly used Java installers from Oracle:

Windows	jdk-25_windows-x64_bin.exe [SHA256]
macOS	jdk-25_macos-x64_bin.dmg [SHA256] jdk-26_macos-aarch64_bin.dmg [SHA256]
Linux	jdk-25_linux-x64_bin.deb [SHA256] jdk-26_linux-aarch64_bin.rpm [SHA256]

Windows Defender or any antivirus software will discourage you to download or install Ancestor Tree Manager. This is a standard response to 'Unknown' software. Perhaps it could be prevented with a Code signing certificate but that is not free. And for free software, that's a bit much to ask. However there is a SHA256 checksum available.

*** Follow the ATM installation instructions for the appropriate platform ***
