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.
