1Password TeamBeta 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 | ✅ | ✅ | ✅ |
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 ask questions and/or provide feedback about the MSIX installer? Feel free to ask your questions and/or provide feedback directly in this thread.
Delay to Microsoft Store release of MSIX installer (1Password for Windows)
Hello 1Password Community!
Last month, we released the new MSIX installer for 1Password for Windows to 1Password.com with plans to release to the Microsoft Store on September 8.
Due to some issues incurred while publishing the MSIX listing, the listing has not yet been made available in the Microsoft Store. We are working to get the new listing published as soon as possible. Future updates will be provided in this thread.
Thank you for your patience!

We have been actively working with Microsoft and troubleshooting over the past few weeks in order to get the new application certified and published in the Microsoft Store ASAP.
While the new app may get certified and published sooner, we are currently estimating a mid-October release for the MSIX in the Microsoft Store. Until then, only direct downloads of the MSIX and App Launcher from the 1Password website are available.
My apologies to any inconveniences caused by this delay! Will continue to provide updates as we get them.

Now that the MSIX has been released to Stable, upon updating to the latest version, you should be able to switch to the Stable release channel within Settings!
You can also download the MSIX from the 1Password site. For anyone who needs the App Installer, you can find it here.
The official date for the Microsoft Store release will be September 8.
A huge thanks to everyone for trying out the beta!
Any chance you'll share adoption metrics of the MSIX version? I get that it's niche, but I'm curious.
- 1P_justin
Hello! We don't have plans to publicize adoption metrics of the MSIX. We do have plans to deprecate the EXE in the near future and migrate users to the MSIX (or MSI if system requirements are not met for the MSIX).
I’m having trouble using Windows Passkey. Has anyone found a solution to this issue?
I recently noticed that ever since the last update, 1Password no longer opens on startup. I have checked my settings both in Windows and in 1Password, but it's still not opening when it's supposed to.
The problem is, right now, that you have to configure it for 1Password every time it had an update.
The new version sets an entry in `HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run`, that's version specific, so if it doesn't update the entry itself every time it updates you have to configure it again.
For Store Apps (UWP) there is another option, which 1Password doesn't use:
- https://learn.microsoft.com/en-us/uwp/api/windows.applicationmodel.startuptask
- Example reg key: `HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\SystemAppData\{ApplicationIdentifier}\{App}.StartupTaskId\State`

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.

This is something that we are currently aware of and working to fix! :) Thanks for sharing.
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.

Thank you very much for sharing! I'll bring this up to our developers 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?
- 1P_justin
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?
