Summary
On August 5th, 2025, the MSIX installer for 1Password for Windows was released. This new installer combines the benefits of our existing EXE and MSI installers, so you don’t have to choose between features previously exclusive to a single installer. The MSIX installer also offers several benefits over to the EXE installer, including support for Windows for ARM and improved installation protection.
Later in October, the EXE installer will be deprecated and removed as an installer option. We recommend that all customers use the MSIX installer where possible. However, we’ll continue to support the MSI installer for customers who need it.
What to know
- The MSIX installer is now available for download on 1Password.com and will be available through the Microsoft Store starting on September 8th, 2025.
- If you want access to beta or nightly releases, you should use or deploy the MSIX installer found on 1Password.com.
- The MSIX installer will require Windows 10 20H1 or later. If you use an earlier version of Windows 10, you should use the MSI installer instead.
- If you want to update to the MSIX installer, we recommend that you uninstall 1Password for Windows first, then reinstall it with the new installer.
If you used the EXE installer or the Microsoft Store
If you installed 1Password using the EXE installer or the Microsoft Store, and you have “Install updates automatically” turned on, you’ll need to switch to a supported installer depending on your version of Windows:
- If you use Windows 10 20H1 or later, 1Password will automatically update to the MSIX installer later this year with no action required.
- If you use Windows 10 19H2 or earlier, you’ll be prompted to update to the MSI installer later this year.
To install the update to the MSI installer, you’ll need administrator privileges for your PC.
If you deploy the MSI installer to your team
If you deploy 1Password to your team with the MSI installer, you can continue to do so, and you don’t have to switch to the MSIX installer unless you choose to.
Tip
As of 1Password for Windows 8.10.72, the MSI installer supports in-app updates, which are turned on by default. You can review the deployment options to see how you can control the MSI installer.
If you deploy the EXE installer to your team
If you deploy 1Password to your team with the EXE installer, you should switch to the MSIX installer. You can download the MSIX installer on 1Password.com or wait to deploy 1Password through the Microsoft Store starting on September 8th, 2025.
If you deploy to computers running a version of Windows earlier than Windows 10 20H1, you can use the MSI installer instead.
