1Password not starting on Win10 Anniversary [Fixed by updating Windows]

New install of 1Password on Win10 Anniversary doesn't start. Tried uninstalling and reinstalling, verified Net Framework 4.6.2 installed. Will attach errors from event viewer.

EventLogLogger App exception 0x80131534.

Hi @emerillat,

Thanks or reporting this.

Have you tried updating Windows to Creators Update? Anniversary Update is already outdated by several months and Windows 10 Creators Update came with .NET 4.7 update already installed.

Your error is very unusual, it looks as if two separate versions of .NET versions are mixing each other up, it shouldn't be possible. However, it is possible you can get this fixed by updating Windows first.

Thanks for the response. After manually running Windows Update (this machine normally gets its updates from WSUS) 1Password is now working.
