Your machine	File
Windows 11 (x64)	Stem-Studio-1.1.0-win-x64.exe

macOS and Linux builds are published separately under the tagged v1.1.0 release.

Install on Windows

1. Download the .exe and (optionally) verify it against SHA256SUMS-windows-x64.txt:
   certutil -hashfile Stem-Studio-1.1.0-win-x64.exe SHA256
2. The build is unsigned, so SmartScreen will warn: click More info → Run anyway.
3. The installer runs per-user — no admin rights needed. On first run the app provisions its managed, on-device separation runtime (bundled FFmpeg; Python fetched into your user data folder). No admin rights and no system Python or FFmpeg required.

Notes

• This is a prerelease, unsigned build. Verify the checksum before installing.
• The bundled FFmpeg is GPL-3.0-or-later. Its corresponding source archives, the SPDX/CycloneDX SBOMs, media provenance, and third-party license/notice files are attached alongside the installer (see THIRD_PARTY_NOTICES.md, MODIFICATIONS.md, and FFMPEG_SOURCE_OFFER.md).
• Stem separation uses the TIGER model; its Apache-2.0 and upstream MIT license texts are attached.
