Beta Release: New MSIX Installer for 1Password for Windows

Hello 1Password Community!

We are excited to announce the beta launch of the MSIX installer for 1Password for Windows. The MSIX installer combines the benefits of our existing EXE and MSI installers, meaning that you no longer need to compromise between features that are exclusive to the EXE or MSI. Like MSI installations, MSIX installs to a directory that requires admin privileges to modify, providing additional tamper-proofing measures. In addition to this, MSIX offers an improved ability to detect other common forms of tampering, notifying the user and giving them the option to repair or reset the install.

	EXE	MSI	MSIX
Protected install*	❌	✅	✅
Improved tamper detection	❌	❌	✅
ARM64 support	✅	❌	✅
In-app updates	✅	✅	✅
Access to Beta and Nightly channels	✅	✅	✅

*Protected install refers to installing in a directory requiring admin privileges to modify, providing additional tamper-proofing measures against threats such as local malware.

Accessing the Beta:

We’d love for you to try out the MSIX beta and provide feedback about your experience. To try out the beta, first make sure that you are running Windows 10 20H1 or later. Then, download the installer by clicking on this link and install 1Password.

Additional Notes:

When will the MSIX be officially released? We are looking to officially launch MSIX in late-June of this year, both as a direct download from our website and via the Microsoft Store.

Do I need to uninstall 1Password before installing the MSIX version? It’s recommended but not required. Once the MSIX is installed, you’ll no longer be able to open other versions of 1Password and will be prompted to uninstall old versions, if opened.

Can I use the MSIX beta long-term? Yes! Over the course of the beta, you’ll be locked to the beta channel, but once the MSIX is officially released, you will be able to switch to Stable and Nightly channels upon updating.

Where can I learn more about MSIX? Check out this Microsoft article on MSIX to learn more.

Where can I ask questions and/or provide feedback about the MSIX installer? Feel free to ask your questions and/or provide feedback directly in this thread.

MSIX - Stable Release Update
First and foremost, thanks to everyone trying out the MSIX beta. Your involvement and feedback has pivotal in helping us identify issues and improvements in advance of the stable release!
In order for us to address all issues in advance of the stable release, we've pushed back the stable release of the MSIX installer to:
Direct download from 1Password.com: August 5, 2025
Microsoft Store: September 2025 (exact date TBD)

** Microsoft Store Note: The MSIX version will be listed in the Microsoft Store as a new application and the current listing will be delisted. We expect devices to treat the new listing as a separate application and recommend uninstalling the EXE version to prevent two instances of 1Password from being installed.
As mentioned in the original post, you can continue to use the MSIX beta version through the stable release. When the stable releases, you'll see an option to switch over to the stable release channel.

This obviously isn't a huge deal but it is a little annoying. The MSIX version has a square background of the Windows accent color for the app icon. It's really obnoxious.

  This is because the current MSIX package only has a single icon in the assets (BETA@64x64.png) and not the full collection (https://learn.microsoft.com/en-us/windows/apps/design/style/iconography/app-icon-construction#complete-list-of-icons-and-variations) that windows expects - should be pretty easy to fix.

Hi everyone, I managed to fix the browser integration with the MSIX version. After looking at the logs, I saw that the browser extension was erroring on finding the path of the application, specifically because the Drive was different:
ERROR 2025-06-05T12:26:10.140+00:00 [1P:op-ipc\src\ipc\windows.rs:436] peer process and app install paths are not the same. peer process path: E:\WindowsApps\Agilebits.1Password_8.10.80.18_x64__gh85et3mt782r\1Password\app\8 install path: C:\Program Files\WindowsApps\Agilebits.1Password_8.10.80.18_x64__gh85et3mt782r\1Password\app\8 ERROR 2025-06-05T12:26:10.140+00:00 [1P:native-messaging\op-browser-support-lib\src\communication_logic.rs:201] Failed to connect to the main app: PipeAuthError(InvalidPeerProcessPathLocation)
This was because I had changed where Windows should install applications by default, and by doing so, Windows creates a symlink in C:Program/Files/WindowsApps/ to the drive we setup.
You can check this setting in "Settings -> System -> Storage -> Where new content is saved". After resetting the location to C: and reinstalling, it's working perfectly.
Hopefully, this helps anyone with the same issue and the 1password team as well.

Attention MSIX beta users!
On June 11 (tentative), we will be releasing version 8.10.82 to the beta channel. With this release, we will be updating the certificate used to verify 1Password for Windows installations as genuine 1Password applications.
Due to this certificate update, upon installing the upcoming update to 1Password, you may see a second instance of 1Password installed on your device. Upon running the updated version of 1Password, any older versions of 1Password detected on your Windows device should automatically be uninstalled and you should be able to use 1Password as normal.
If you run into any issues following the next update, we recommend first checking for any outdated instances of 1Password that may still be installed and uninstalling them. If issues continue to persist, we recommend uninstalling all instances of 1Password on your Windows device and reinstalling using the updated MSIX package that we will provide in this thread upon release.
We want to thank you again for trying out the MSIX beta and look forward to hearing more of your feedback.

  Hi Justin, will you be able to advise in advance which browser extensions are supported with 8.10.82?

    Hello! When you say browser extensions, what do you mean exactly? All of the MSIX beta versions are intended to work with the latest versions of our browser extensions across Chrome (and Chromium-based browsers like Edge) and Firefox. While we've seen that one person has experienced some issues with the browser integration, this is not something that we've seen others experience with the MSIX so far.

I tried to install it, as the current beta seems to keep closing by itself (possibly crashing) today. However I got the following message when I tried running it.

  Hello! Thanks for trying things out. I think what's happening is that with yesterday's Stable update, that your existing version of 1Password is newer than the one in the download link in the post.
  
  Here's the newest version of the MSIX . I think you should be good once you install this version.

    Hi Justin, would love to test the MSIX. Does this newest version fix the browser extension connection issue?

It looks like the version of the installed msix package is part of the installation path.
The following ends up in my .gitconfig when configuring commit signing:

[gpg "ssh"] program = C:\\Program Files\\WindowsApps\\Agilebits.1Password_8.10.78.39_x64__gh85et3mt782r\\1Password\\app\\8\\op-ssh-sign.exe

Basically this means that you'd have to reconfigure commit signing after every update, which is far from ideal.
Note that there will be a linked executable in the userprofile. i.e. %localappdata%\Microsoft\WindowsApps\op-ssh-sign.exe. It will probably be on the path by default. The automatic process of editing the .gitconfig file should act accordingly.

Installed the MSIX version to test the new passkey feature once Windows enables it, and it seems like the browser connection has broken. It keeps asking for the password, even with the application unlocked.
Retried with the normal .exe and it works flawlessly.

  The browser integration is working for me, but 1Password does ask for the account password when restarted instead of just requiring my PIN, as set in the settings.
  This is reproducible on both of my PCs.
  The regular install didn't have this issue.

If I want to install MSIX version should I remove 1Password EXE/MSI installed version? Secondly will be some restrictions, limited functionality with MSIX installed 1Password? For an example Yubico Authenticator from Microsoft Store doesn't let to change PIN or read from device saved credentials, I can't remember. But if you install from website exe version then there is no issue.

  Hello! As mentioned in the post, we recommend removing the EXE/MSI installed version but it is not mandatory. Once the MSIX is installed, you’ll no longer be able to open other versions of 1Password and will be prompted to uninstall old versions, if opened.
  
  In regards to functionality restrictions, some minor functionality will not work with the Microsoft Store MSIX installed versions of 1Password. Currently, we have determined that 'drag and drop' and 'Type in Window' filling functionality will not be available with the Microsoft Store version. However, this functionality will continue to work for directly downloaded MSIX installed versions.

The MSIX version runs without any issues, but it doesn't seem to update. After restarting 1Password manually, it is still on the same 8.10.74 version.
1Password for Windows 8.10.74 (81074019)
edit: nvm, saw https://www.reddit.com/r/1Password/comments/1ka1vf8/comment/mpuveag/ in the reddit post.
That's great to hear. We've determined that 1Password is trying to download and install yesterday's Stable release, which is intended, but since the MSIX is locked strictly to the Beta channel, it's erroring out when trying to install the update.
There is a Beta release scheduled for today that you should have no issues updating to. Continue to try updating 1Password and any Beta releases should successfully update.

  Same problem, but within the Beta-Channel - The update doesn't work ("Restart Now" does nothing and a manual restart does nothing either)
  When I try to install (=update) the new MSIX manually I get the following error message:
  App installation failed with error message: Windows cannot install package Agilebits.1Password_2025.610.2025.0_neutral_~_amwd9z03whsfe
  because a different package Agilebits.1Password_2025.523.1801.0_neutral_~_gh85et3mt782r
  with the same name is already installed. Remove package Agilebits.1Password_2025.523.1801.0_neutral_~_gh85et3mt782r before installing. (0x80073cf3)

    The `PackageFamilyName` changed between these two versions:
    - `8.10.80.18`: `Agilebits.1Password_gh85et3mt782r`
    - `8.10.82.27`: `Agilebits.1Password_amwd9z03whsfe`
