Geckofx-Core - System.DllNotFoundException

Question

I Integrated Geckofx45.64 in my Windows Forms Application - On some Windows10 distributions i get the following error right after startup:

System.DllNotFoundException
at Gecko.Xpcom.Alloc(IntPtr)
at Gecko.nsAString..ctor()
at Gecko.nsAString..ctor(System.String)
at Gecko.Xpcom.Initialize(System.String)
at Vault_Forms_App.Program.Main

Can anyone help me out with this?

Have a customer with the same problem using GeckFfx60.64 package. Anyone know which redistributable is needed? — Tom Bogle, May 13 '20 at 15:11

The solution can be found https://bitbucket.org/geckofx/geckofx-45.0/issues/194/unable-to-load-dll-mozglue.

With the latest version of geckofx-45, for some reason the files msvcp120.dll and msvcr120.dll are missing in the Firefox folder. You can either copy them from an older version or install Visual C++ Redistributable for Visual Studio 2013

Try to install Visual C++ Redistributable for Visual Studio 2015.
