Downloads

Setup is recommended for normal use. It includes the .NET runtime, so no separately installed .NET is required. It offers a desktop shortcut and Start menu entries. Choose Install all / Choose data / Later for astronomy data; downloads may take several minutes. Install astronomy data… provides the same choices later. Settings, logs and imported data are stored separately under %LOCALAPPDATA%/AmrumSoftware/OrbitWorkbench. The standalone package contains the executable, its source-built core DLL and necessary runtime resources: keep these files together. Large JPL, asteroid and bias files are not bundled. Updates preserve user data and back up the previous program version.

VirusTotal: not submitted. Standalone means the complete portable package, not the executable without its core DLL.
