When upgrading to v8, App unable to start correctly (0xc000005)

Hi DoctorBrown, thanks for reaching out!

Do I need to fix the validation error before I update to v8. How to fix that.

Until you're able to successfully complete this, the app won't be able to sync any changes. As a first step I would recommend checking whether you're able to successfully sign in to this user's account on our website, 1Password.com, and whether they have a complete and up-to-date set of their data present there.

If you are able to sign in, and their data is complete, it's possible that the app may need a reset to clear out any old credentials and allow you to sign in from fresh.

If you're not able to sign in on our website or any data is missing there, let us know and we can give you the steps to email in for our support team to assist further.

Is v8 compatible with Win7 and how to fix the install error.

1Password 8 requires a 64-bit version of Windows 10 or later: System requirements for 1Password

Windows 7, 8, and 8.1 are no longer supported by Microsoft, and this has some significant security implications. We would highly recommend upgrading to Windows 10 or 11 if at all possible, not only for ongoing compatibility with 1Password, but also because of significantly improved security features within Windows itself.

If you're not able to upgrade to Windows 10 or 11, the most up to date way to continue using 1Password on this VM will be to use the latest 1Password browser extension along with our website for any tasks that would usually require the desktop app, such as manually making edits to your items.

Let me know how you get on!
