--- Comment #4 from Anastasius Focht <focht at gmx.net> ---
Hello Ilnar,

Maybe it's happening because the programm cannot start default browser, IE for
simple?
--- quote ---

Likely not, it's using the Chromium Embedded Framework (CEF) which provides an
own browser implementation. It used managed wrappers for .NET from this
project:

http://cefsharp.github.io/

NET (WPF and Windows Forms) bindings for the Chromium Embedded Framework 

https://github.com/cefsharp/CefSharp

The callout from managed code to unmanaged:

https://github.com/cefsharp/CefSharp/blob/05b37ab61583cbc3c7aa2ce6dce42bf83bbce945/CefSharp.Core/Cef.h#L190

--- snip ---
...
            CefMainArgs main_args;
            CefRefPtr<CefSharpApp> app(new CefSharpApp(cefSettings,
browserProcessHandler));

auto success = CefInitialize(main_args, *(cefSettings->_cefSettings),
app.get(), NULL);
...
--- snip ---

Unmanaged (pinvoke) entry declaration:

--- snip ---
  [SuppressUnmanagedCodeSecurity]
  [MethodImpl(MethodImplOptions.Unmanaged | MethodImplOptions.PreserveSig,
MethodCodeType = MethodCodeType.Native)]
  [return: MarshalAs(UnmanagedType.U1)]
  internal static extern unsafe bool CefInitialize([In] CefMainArgs* obj0, [In]
CefStructBase\u003CCefSettingsTraits\u003E* obj1, [In]
scoped_refptr\u003CCefApp\u003E* obj2, [In] void* obj3);
--- snip ---

No idea since I don't come that far. Could be some interop marshalling problem
in the platform invoke for the 'libcef.dll.CefInitialize' entry point. Maybe
some object reference is invalid due to earlier problems.

You could try with native (Microsoft) .NET Framework 4.6.x using 'winetricks'.

Be aware installation of MS .NET Frameworks 4.x via 'winetricks' is broken
again in recent Wine versions due to MSI regressions. The frequency of MSI
regressions really *** me off so I didn't bother to look anymore.

Regards
