The 1Password for Windows installer does not install on Windows 11

Downloaded 1PasswordSetup-latest.exe file version 8.10.9.46 to install on Windows 11 Business version 10.0.22621 on a Lenovo 21BT001PUS running a 12th Gen Intel i7 with 16Gb RAM. Ran the file with Administrator permission. It asked to install 1Password 8, and I clicked OK. At about 80% through the installation it stopped and brought up a dialog box saying “1Password was unable to complete installation and will roll back any changes.”


1Password Version: 8.10.9.46
Extension Version: Not Provided
OS Version: Windows Business 11 ver 10.0.22621

I have the same problem on my ThinkPad E15 a personal account.

I had initially installed on Windows 11 and it was working fine but then it wouldn't install any updates. I tried uninstalling the app, downloading the new installer, and now it won't install at all. I'm now without 1password on my Windows machine. Multiple reboots haven't helped either.
Windows 11 Home, 22H2, build 22621.2134

Edit: found in another thread, rebooting windows in Safe Mode and then running the installer worked. I'm now back in business. Phew! What a hassle though; am I going to have to do this every update?

Hello folks,

I'm sorry for the issues you've encountered with the installation of 1Password for Windows.

Since @thunderpaw mentioned that restarting Windows in Safe Mode with Networking Enabled and installing 1Password again, helped, you are likely running into security software that was blocking the app from completing the install. @Headley / @aryehby - I've left Microsoft's Support guide below for assist if you'd like to give this a try:
* Start your PC in safe mode in Windows - Microsoft Support

If this helps, you can try updating security software and excluding the 1Password.exe file from scans. This can help to ensure you don't run in to future troubles with installs or updates. The .exe can be found here - C:\Users\%username%\Appdata\Local\1Password\app\8\.

Please let me know if you encounter any other troubles.

I had same exact issue while installing 1password. 
Went to location mentioned above (not in safe mode) executed the mixundle file with appinstaller. 
Asked to reinstall and then launched the application, I can now see I have the latest release 8.1.12.1

Attached logs here for reference. I think i am not allowed to attach .zip files

I hope 1password team  add one more special place (text area) in members replies, where they can attach sensitive information, like logs or other screenshot etc

I have seen this of many discussion forums.
