Install

Three steps, about a minute.

Pick the file you downloaded. The installer is the easy route; the zip is for people who like a folder they can move around.

01 · OPEN

Open the installer

Click Engone-Demo-Setup-0.9.8-build2.exe in your browser's download list, or double-click it in your Downloads folder.

02 · WINDOWS CHECK

More info → Run anyway

Windows asks once because the game is new and not code-signed yet. What it looks like is shown below.

03 · INSTALL

Install, then Launch

No admin password needed. When it finishes, Engone Demo is in your Start menu and on your desktop.

Mock-up of the Windows dialog. It shows once, the first time you open the file.

WHY WINDOWS WARNS YOU

Click More info, then Run anyway.

Windows shows this for new programs that aren't signed with a paid code-signing certificate. Engone is made by an independent developer and isn't signed yet — the warning is about the missing signature, not about anything found in the file.

Want to be sure you have the genuine file? Compare its SHA-256 checksum with the one on this page.

EDGE / CHROME If the browser says the file “isn’t commonly downloaded”, open the download list, click … next to the file and choose Keep (then Keep anyway).

The Hash it prints should match the value above.

Troubleshooting

If something doesn't start.

Most problems are one of these. If yours isn't, the Discord is the fastest way to get it fixed.

“Windows protected your PC” stops the game from opening

Click More info, then Run anyway. It's a one-time check for programs that aren't code-signed yet — see the walkthrough.

My browser blocked the download or says it “isn't commonly downloaded”

Open your browser's download list (Ctrl+J), click … next to the file, and choose Keep, then Keep anyway. New files from small developers get this until enough people have downloaded them.

My antivirus removed or quarantined the file

New, unsigned game builds sometimes trip antivirus heuristics. Restore the file from quarantine (or allow it), then check its SHA-256 against this page. Tell us which antivirus flagged it in the Discord so we can report the false positive.

The game closes straight away, or says it can't find its data

You are probably running it from inside the zip. Right-click the zip, choose Extract All, and run ENGONE_Demo.exe from the extracted folder. Keep ENGONE_Demo_Data next to the .exe — or use the installer, which handles this for you.

Black screen, or a very low frame rate

Update your graphics driver first. On a laptop, make sure the game uses the dedicated GPU: Settings → System → Display → Graphics, add ENGONE_Demo.exe and pick High performance. Alt+Enter switches between fullscreen and windowed.

I'm on a Mac, Linux or a phone

The demo is Windows-only for now. Send yourself the link — engone.dev/demo — and download it on a Windows PC.

How do I uninstall it?

Installer version: Settings → Apps, find Engone Demo, and choose Uninstall. Zip version: delete the folder. Settings and logs live in %USERPROFILE%\AppData\LocalLow\ENGONE if you want those gone too.

Reporting a crash or a bug

Post in the Discord with what you were doing and, if you can, the log file. Paste this into the File Explorer address bar to find it:

%USERPROFILE%\AppData\LocalLow\ENGONE\ENGONE\Player.log
