Fyi, version 600 has been OK for me, but attempting to install any post 600 version including 619 over the existing install results in the following or similar message during program initialisation and hangs: "ex: Could not load file or assembly 'Cefsharp.Core, Version=188.8.131.52, Culture=netural, PublicKeyToken=40c..138' or one of its dependencies The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"
After reinstalling 600 all works OK again.
A new install of say 619 does works OK but I loose a my library entries and I am unsure what relevant files to/not copy to the new install directory. Current using Windows 10 v1703 (15063.502)
