Windows web app tester guide
Thank you for trying Lila Modeler on Windows. On Windows, Lila Modeler is meant to be used as a
web app installed from Microsoft Edge or Google Chrome (ADR-031): it gets its own
window and Start menu entry, opens .lila files on double click and saves back to the same file.
Nobody on the project has done this on a real Windows machine yet, so you are the first: things
may not work, and a clear report of what did and did not work is exactly what we need. You do not
have to be a developer. Set aside about 20 minutes.
Two things to know before you start:
- There is nothing to download and no installer: no SmartScreen warning and no administrator rights. The browser installs the app from the project's website.
- Lila Modeler runs entirely in your browser: no account and nothing is uploaded. Your files stay where you save them.
(The unsigned .exe installer is a separate, secondary option with its own
guide. You do not need it for this one.)
What you need
- Windows 10 or Windows 11.
- Microsoft Edge (it comes with Windows). If you also have Google Chrome, step 12 repeats the main steps there.
- An internet connection for the first visit; step 10 checks that the app then works without one.
Steps
Menu and button names below are the app's English ones. If the app shows up in Spanish, click Ajustes (the gear at the top right) and set Idioma to English, or read the Spanish guide, which uses the Spanish names. Browser menus change a little between versions: if a name does not match exactly, pick the closest one and note it in your report.
- Open the app in Edge. Go to https://alambritodito.github.io/lila-modeler/app/. A white
screen with the Lila Modeler logo and a version number (for example
v1.0.0-beta.22) appears for a moment, then the editor with an example diagram (a restaurant order). Write down the version you saw. - Install it. In the address bar, click the App available icon (a small square with a plus sign or a down arrow), or open the ⋯ menu ▸ Apps ▸ Install this site as an app. The dialog should say Lila Modeler with the purple dog icon; click Install. Edge may offer to pin it to the taskbar or Start; accept whatever you like. The app reopens in its own window, without the address bar.
- Open it from Start. Close that window. Open the Start menu, type
Lilaand open Lila Modeler. It should open in its own window with the purple dog icon in the taskbar. - Run a simulation. Click Simulate in the top bar, then Run simulation. The dock under the canvas shows the quick results when it finishes.
- Save as a
.lilafile. Click File ▸ Save as. The usual Windows Save As dialog opens (not a download). Pick a folder you know (for example Documents), keep or change the name, and click Save. In File Explorer, check that the folder now has a file ending in.lila, and that nothing new appeared in Downloads. - Save again to the same file. Back in the app, click a task in the diagram, change its name
(double-click it and type), and press
Ctrl+S(or File ▸ Save). This time no dialog should appear. If the browser asks whether Lila Modeler may save changes to the file, choose Allow (or Save changes). In File Explorer, check that the Date modified of the same.lilachanged and that there is no second copy. - Open it by double click. Close the app window. In File Explorer, double-click the
.lilafile. Lila Modeler should open in its own window with your renamed task. The first time, Windows may ask which app to use (choose Lila Modeler) and the browser may ask whether Lila Modeler may open.lilafiles (choose Allow; you may tick Remember my choice). If the double-click opens something else or nothing, open the app from Start and use File ▸ Open instead, and say in your report that the double-click failed. - Double-click with unsaved changes. With the project open, change something again (for
example rename another task) and do not save. Double-click the same
.lilain File Explorer again. The app should ask about Unsaved changes with Save and continue, Discard and Cancel. Click Discard: the file reopens as it was on disk, without your last change. - Open from inside the app. Click File ▸ Open. The Windows Open dialog appears; pick
your
.lilaand click Open. Then change something and pressCtrl+S: it should save to that file without asking where. - Use it offline. Close the app. Turn on airplane mode (or unplug the network cable). Open Lila Modeler from Start: it should still open with the editor, and step 4 should still work. Turn the connection back on.
- Uninstall. In the app window, open the ⋯ menu at the top right ▸ Uninstall Lila
Modeler (or App settings ▸ Uninstall; or Settings ▸ Apps ▸ Installed apps in
Windows). Confirm. Check that Lila Modeler disappears from Start. Your
.lilafile stays where you saved it. - Optional: repeat with Chrome. If you have Google Chrome, open the same address in it and install it from the install icon in the address bar (a monitor with a down arrow) or ⋮ ▸ Cast, save and share ▸ Install page as app…. Then repeat steps 3 to 7 and 11 and note any difference.
Report what happened
Please report even if everything worked (“all 12 steps fine” is useful). Use one of these:
- Open an issue at github.com/AlambritoDito/lila-modeler/issues/new and paste the template below. Please do not put anything private in it; screenshots can be cropped to the app window.
- Or send the same text, with the screenshots, by message to the person who gave you this guide.
