1Password fails to update when McAfee Application Control is enabled

When McAfee Application control is enabled it generates no errors and allows installation of 1Password if I were to download and install manually. However, when 1Password tries to update automatically, we get some events from McAfee but no errors. 1Password, however, fails to install and I don't know where to look for logs if any to find out why.

McAfee generated events when it's enabled:

'C:\Users\user\AppData\Local\1Password\update\7\1Password.exe' was unsolidified which was deleted by program C:\Users\user\AppData\Local\1Password\1PasswordSetup-7.9.822.exe(User: user, Workflow Id: SIGNED_UPDATER: 1Password).

McAfee explanation of the events:

"The event being recorded is considered normal behavior for McAfee Application and Change Control. When an updater creates or updates any files, MACC temporarily adds the files to the inventory. Files also included are non-executables (PE32 header). When updaters keep files open while the files change, MACC adds them to the allow list and then removes them from inventory. This process results in the event being generated and recorded in the Windows Event log."

This is the only clue we have. I am posting same question on McAfee support, but I thought I'd post it here where maybe you guys ran into this before or can tell me where to get more info on where and how the updater fails so we can provide more info to McAfee.

Thanks,
Ilya

    Hey @Ilya Voloshin 👋

    Generally-speaking, third party tools like McAfee tend to be a bit overzealous and like lock down entire installation directories, which will prevent applications from updating automatically, such as 1Password.

    Whitelisting %LOCALAPPDATA%\1Password\ within McAfee followed by a quick reboot of your machine should be all you need to do to get automatic updates rolling again.

    Let me know if that helps! :chuffed:
