If the BitBoxApp fails to install on Windows, the issue is usually caused by an incomplete download, Windows security warnings, missing administrator permissions, another BitBoxApp process running in the background, or security software blocking the installer.

This guide helps you resolve BitBoxApp installation problems on Windows and complete the installation successfully.

This article applies if

• The BitBoxApp installer does not open.
• Nothing happens when you open the BitBoxApp installer.
• Windows displays a security warning.
• Windows blocks the BitBoxApp installer.
• The BitBoxApp installation stops before it completes.
• The BitBoxApp still shows an older version after installing the latest version.

Before you continue

Before changing Windows security settings or running the installer again:

1. Delete any BitBoxApp installer that was downloaded from an unofficial source.
2. Check the BitBoxApp operating system compatibility article to confirm that your Windows version is supported.
3. Install available Windows updates if your computer has not been updated recently.

If Windows displays a warning or you want to verify the download before continuing, use the Windows BitBoxApp signature verification guide to confirm that the installer was signed by Shift Crypto.

Download a fresh BitBoxApp installer

An incomplete or damaged download can prevent the BitBoxApp installer from opening or completing.

1. Delete the BitBoxApp installer from your Downloads folder.
2. Open the official BitBox download page.
3. Download the latest Windows installer again.
4. Open the new installer.

The BitBoxApp installer should now open normally. If the installer still does not start, continue with the next troubleshooting section.

Close existing BitBoxApp processes

Only one BitBoxApp instance should run at a time. If the BitBoxApp is still running in the background, the installer may not open correctly or may appear unresponsive.

1. Close the BitBoxApp.
2. Open Windows Task Manager.
3. Check whether a BitBoxApp process is still running.
4. End any remaining BitBoxApp process.
5. Run the BitBoxApp installer again.

The installer should now open normally and continue with the installation.

Run the installer as administrator

Depending on your Windows configuration, administrator permissions may be required to install software.

1. Locate the downloaded BitBoxApp installer.
2. Right-click the installer.
3. Select Run as administrator.
4. Confirm the Windows permission prompt.
5. Continue the installation.

Windows should now install the BitBoxApp successfully.

If you use a work, school, or otherwise managed computer, you may need permission from the device administrator before installing the BitBoxApp.

If Windows SmartScreen blocks the installer

Windows may display a SmartScreen warning such as Windows protected your PC.

This warning does not automatically mean that the BitBoxApp installer is unsafe. If you downloaded the BitBoxApp installer from the official BitBox download page, you can safely continue with the installation.

If you would like additional confirmation before bypassing the Windows SmartScreen warning, you can verify the installer using the Windows BitBoxApp signature verification guide.

To continue with the installation:

1. Select More info.
2. Select Run anyway.
3. Continue the installation.

Check antivirus software or managed device policies

Microsoft Defender (Windows Defender), third-party antivirus software, endpoint protection tools, browser security settings, or company device policies can block the BitBoxApp download or installer.

1. Check whether Microsoft Defender (Windows Defender) or another antivirus solution has quarantined or blocked the BitBoxApp installer.
2. Check whether your browser blocked the downloaded installer.
3. If you use a managed work or school computer, ask your device administrator whether software installation is restricted.
4. Download the latest BitBoxApp installer again after the block is resolved.
5. Run the installer again.

The BitBoxApp installer should now be allowed to run and the installation should complete.

If the BitBoxApp still shows an old version

Running the latest Windows installer normally updates the existing BitBoxApp installation. If the BitBoxApp still shows an older version after installing:

1. Close the BitBoxApp completely.
2. Open the BitBoxApp again.
3. Open Settings.
4. Open About.
5. Check the displayed BitBoxApp version.

If the old version still appears:

1. Uninstall the BitBoxApp from Windows.
2. Restart your computer.
3. Download the latest Windows installer from the official BitBox download page.
4. Install the BitBoxApp again.
5. Open Settings.
6. Open About.
7. Check the displayed BitBoxApp version again.

The BitBoxApp should now show the newly installed version.

Frequently asked questions

Why does nothing happen when I open the installer?

This can happen when another BitBoxApp process is still running in the background or when security software blocks the installer. Close any BitBoxApp processes in Task Manager and check whether Windows Security, your browser, or another security tool blocked the file.

Why does Windows say "Windows protected your PC"?

This warning is generated by Windows SmartScreen. If you downloaded the BitBoxApp installer from the official BitBox download page, you can safely continue with the installation. For additional confirmation, you can verify the installer signature before selecting Run anyway.

Do I need administrator permissions to install the BitBoxApp on Windows?

Possibly. Depending on your Windows configuration, administrator permissions may be required to install the BitBoxApp. On managed work or school computers, your device administrator may need to approve the installation.

Can antivirus software prevent the BitBoxApp from installing?

Yes. Microsoft Defender (Windows Defender), third-party antivirus software, endpoint protection, browser security settings, or managed device policies can prevent the BitBoxApp installer from downloading, opening, or completing.

Can I update the BitBoxApp by installing the latest Windows version?

Yes. In most cases, running the latest Windows installer updates the existing BitBoxApp installation.

Will reinstalling the BitBoxApp remove my funds?

No. Reinstalling the BitBoxApp does not remove your funds. Your cryptocurrencies remain on their respective blockchain, while access to them is secured by your BitBox02 and your wallet backup.

Does Windows on ARM support the BitBoxApp?

Windows on ARM is not recommended. The BitBoxApp may run through emulation, but this setup can cause slow performance, unresponsive behavior, or long loading times.
