A couple of scanners on VirusTotal may flag this build with a generic machine-learning heuristic (names ending in .ml or "ml.score") rather than a signature-based malware match. This is a known, common false positive for unsigned, independently built Tauri/NSIS installers with no download history yet, and no signature-based engine flags it.

Windows 10/11, 64-bit, v1.5.0. See the changelog for release notes.

Having Trouble Installing?

Seeing a blue "Windows protected your PC" screen?

That's expected, not a sign something is wrong. Here's why it shows up and how to get past it.

Windows protected your PC

Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.

App: QAlchemy_1.5.0_x64-setup.exe
Publisher: Unknown publisher
More info Don't run

A recreation of the Windows SmartScreen dialog, for reference.

1

Click "More info"

A "More info" link appears in the dialog. Click it to reveal a "Run anyway" button.

2

Click "Run anyway"

This confirms you want to proceed. The installer will launch normally right after.

3

Install as usual

Follow the setup wizard. This warning only appears on first run, not every launch.

This warning is standard for independently published Windows apps that haven't purchased a paid code-signing certificate, not a sign of malware. QAlchemy is built and maintained independently by its creator, and this installer is served directly from this site. It's safe to click through.

Ready when you are.

One installer, a local workspace, and your own AI provider. That's the whole setup.
