Your browser may save the installation file automatically or show a Save dialog. Choose where to keep it, then select Save. If the browser offers Run or Open, it can open the installer after the download finishes.

In most Windows browsers, Ctrl+J shows current and recent downloads. You can also choose Downloads from the browser menu or look in your PC’s Downloads folder. If you chose another folder when saving, look there instead.

Small installers may take only a few moments. Larger apps and data files can take longer, depending on your connection. Your browser shows the actual progress and any error messages.

A ZIP packages a large app and its data into one compressed file. Once it has downloaded, right-click it, choose Extract All, and run the setup or installation .exe from the extracted folder.

The downloaded file is the installer. Opening it installs the app; downloading it alone does not. Follow the on-screen instructions, and choose a desktop shortcut if offered.

A newly rebuilt installer can trigger a Microsoft Defender SmartScreen reputation message even when it is digitally signed.

Check that you downloaded the intended installer from Dauntless. Select More info to review the publisher. Our Windows apps are signed by Dauntless Aviation LLC. If the details match, Run anyway may be available.

If a specific threat is reported, the publisher is different, or your organization blocks the app, contact our helpdesk or your IT team before continuing.

More about Dauntless installers and security messages

“Do you want to allow this app to make changes to your device?” is a User Account Control prompt. Windows is asking for permission to install. Review the app and publisher, then choose Yes if they match the Dauntless installer you intended to run.

Some PCs require administrator permission. If appropriate, right-click the downloaded installer and choose Run as administrator. Work, school, and other managed PCs may require your local IT support team to install it for you.

Read our installation security guidance

If Windows says the app is not Microsoft verified, or only allows Microsoft Store apps, check where your PC allows apps to come from.

• Windows 11: Start > Settings > Apps > Advanced app settings.
• Windows 10: Start > Settings > Apps > Apps & features.

Under Choose where to get apps, select an option that permits apps from outside the Store, such as Anywhere. Older Windows 10 versions may use Allow apps from anywhere or Turn off app recommendations. You can search Settings if the wording differs.

Windows in S mode is different: it only runs Microsoft Store apps. Switching out of S mode is free, but permanent. Review Microsoft’s S mode instructions, or ask your IT team on a managed PC.

If Windows still says it cannot run or install the app, contact us with the exact message. Other compatibility or administrator restrictions may apply.

Our Windows installers are digitally signed using an Extended Validation certificate from DigiCert and are regularly scanned for security and integrity.

The signature helps you verify that the installer comes from Dauntless Aviation LLC. A new build can still display a Windows reputation warning while it becomes more widely downloaded.

How to check the publisher and certificate

This download is the Microsoft Windows PC version. It will not install directly on macOS, iOS/iPadOS, Android, or ChromeOS.

Versions for other devices are available for many of our products. Visit our products page to check the options for your device.

If you are intentionally saving the installer for a Windows PC, you can still download the Windows file.
