Windows · if it says it's blocked
Getting past the Windows warning.
Right-click the downloaded zip, choose Properties, tick Unblock at the bottom, click OK. Then right-click, Extract All, and run ATLAS-17.exe.
Click More info, then Run anyway. It shows up because the app is new and not signed by a big publisher yet.
That's Windows Smart App Control, which only allows signed apps. Use the browser install instead: open atlas17z.fund/companion in Edge or Chrome and click Install app in the address bar.
Android · same companion on your phone
Keep it in your pocket too.
Tap the Android download. It comes straight from us, not the Play Store, so that's expected.
If your phone blocks it, tap Settings, turn on "Allow from this source" for Chrome, then go back. If Play Protect warns you, tap More details, then Install anyway.
iPhones can't install this file. Open atlas17z.fund/companion in Safari, tap Share, then Add to Home Screen.
