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.

Not sure what's the current state of this issue, but I just stumbled upon this exact issue. I wasn't able to get the Chrome extension to connect to the app as well as using the recently announced Passkey feature for Windows.

I got similar logs to the ones above, which reminded me that I recently moved (possibly by uninstalling and reinstalling) the app from drive C: to D:. I tried moving the app back to drive C:, and this issue magically disappeared.

In case if you still need any help, I'm happy to provide additional debugging information. Please let me know.

I’m having trouble using Windows Passkey. Has anyone found a solution to this issue?

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.

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).

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!

Check out this page to learn more about the MSIX installer.

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.

MSIX is now live in the Microsoft Store!

Thank you everyone for your patience.

I installed this MS Store version and uninstalled my previous exe version. Having a few issues since then:

1Password extension isn't able to detect / connect to this version. I keep getting "Integration status: Connection problem. Please make sure the 1Password app is unlocked." The app is unlocked. I also tried disabling -> enabling the "Connect with 1Password in the browser" setting in the app. Had no effect.
I'm not seeing any "Settings -> Autofill" option, as mentioned in this article for passkeys.
"Access to Beta and Nightly channels" - Not seeing this either.

Thanks so much for sharing. I'll take this back to the team and we will look into these issues!

I installed 1Password from https://apps.microsoft.com/detail/9nzws5x28p0j yesterday, and that was having issues. So I uninstalled that and installed via msix from https://1password.com/downloads/windows. But the issues are continuing.

💻 System Setup

Windows 11 Pro x64, 25H2 (26200.6725)
1Password installed via MSIX bundle (v8.11.14.20 BETA)
Browser Extension: 8.11.12.27 in Chrome, Edge
Windows Settings -> System -> Storage -> Where new content is saved -> New apps will save to > D drive

🪳 Problems

Even though I have my system set to install to D: drive, the msix is installing 1P to C: drive.
After installation and login into the app, when I go to the browser extension, it can't connect to the desktop app and throws this error -
I've uninstalled both browser extensions and the msix app and re-installed them fresh. Same connection issue continues.
1P Settings > Autofill > Passkeys option is greyed out.
And 1P doesn't show up in Windows Settings -> Accounts -> Passkeys -> Advanced options.

📄 Logs

(Editor not letting me enter the code)

❓Questions

Is there a supported way to reinstall the MSIX bundle to a specific drive (e.g., D:) and ensure all components follow that path?
Is this IPC path mismatch a known issue with MSIX installs across multiple drives?
Can the browser stub be forced to launch from the same drive as the desktop app?

Would love any insight from the team or other users who’ve dealt with this.

Thanks in advance!

p.s. Before trying out these MSIX versions, I had the exe version installed for months and that was working fine with the browser extension.

This really helped me a lot.
After I updated to the lastest MSIX version of 1Password today, I found that the browser extension could not connect to the app no matter what I tried, whether reinstalling or rebooting.
It was only when I followed your instructions and checked that I discovered I had changed the default Windows installation location for new apps to drive D.
After moving 1Password back to drive C, the problem disappeared and everything worked normally.
