1Password was unable to complete installation - Windows 10

Hello @JoeRobens and beirne,

I'm sorry to hear of the troubles you've both been experiencing with the installation of 1Password 8 for Windows. I'm happy to assist.

The biggest reason we see this issue is due to 1Password being blocked by another program like Anti-Virus or Anti-Malware Software, such as Norton, McAfee, MalwareBytes, etc. Sometimes a pending Windows 10 update can also cause issues.

Could you try restarting Windows in Safe Mode with Networking Enabled and then try installing 1Password again to see if this helps with this behaviour?

If this helped, as a next step, you can try excluding the entire 1Password folder and the 1Password.exe in any security software you have running and then rebooting your device. This should help with future updates. The 1Password directory can be found here - %localappdata%\1Password and the 1Password.exe is here: %localappdata%\1Password\App\8.

If you run into any other troubles or these steps did not help, please let us know so we can investigate further. Thanks!
