The 1Password update to 6.6.439 fails on my Windows 10 PC. 1Password goes through the downloading step, then closes 1 Password. There is no update file in the Downloads folder and an update is not running in the background. I am running 1Password on multiple devices including a Mac (Family license, I think).
I've tried the update when running 1Password as Admin. I don't have a connected tablet or stylus. I don't see any evidence that Bitdefender is stopping the update.
1Password Version: 6.1.308d
Extension Version: 220.127.116.11
OS Version: Win 10 Pro 64-bit v 1607 build 1480
