I am using Windows 10 on my PC, and keep getting the message the 1Password couldn't update.

Thanks for these @Ruggles, sometimes anti-malware programs can cause this problem, but I'd much prefer if we could go through this with you directly on a 1:1 basis so we can figure out what's going on here.

Could you write in at support+windows@1password.com and reply here with your conversation ID? It'll look like this: ABC-12345-789

We can then pick things up with you and get 1Password updated normally. :)
