• What version of the product are you using?
  CEFsharp.WinForms v49.0.1, cef.redist.x64 (and x86) v3.2704.1418
  • What version are you using? Nuget? CI Nuget? build from a branch? If so which branch?
    Nuget package manager 3.4.4 from Visual Studio 2015 Version 14.0.25421.03 update 3
• What architecture x86 or x64?
  Tried both, both with same error.
• On what operating system?
  Windows 10
• Are you using WinForms, WPF or OffScreen?
  Winforms
• What steps will reproduce the problem?
  any call to CEF will produce this error. CefSharp.Cef.Initialize() crashes the VSTO plugin i'm building.
• What is the expected output? What do you see instead?
  no output available.. i have a Windows Form that needs a browser to an external management page but anywhere i try to initialize CEF it crashes saying it can't find the core.dll or dependency.
• Please provide any additional information below.

  • Does the cef log provide any relevant information? (By default there should be a debug.log file in your bin directory)
    i have no log in my BIN dir.. how do i enable that?
  • Any other background information that's relevant? Are you doing something out of the ordinary? 3rd party controls?
    Only other addin i have is Auth0. i just installed cefsharp.winforms through the nuget package manager that's built into visual studio, added cef.initialize() and even with that being the only line of CEF in my code, gives the above error. i removed the bin directory completely, rebuilt the app, it starts fine but crashes when i open the form that holds the initialize() line. Files from the bin directory (x86\debug) are looking complete:

• Does this problem also occur in the Cef TestApp from http://cefbuilds.com?
  no, the testapp runs fine!

any call to CEF will produce this error. CefSharp.Cef.Initialize() crashes the VSTO plugin i'm building

VSTO is not supported. You'll need to use CefGlue or ChromiumFx.
