Clang Code Model: Error: The clangbackend executable "C:\Qt\Tools\QtCreator\bin\clangbackend.exe" does not exist.

Hello,

yesterday I have updated the Qt Creator to version 4.11.1 and the code completion and syntax highlighting does not work. At the start the Qt Creator writes this: "Clang Code Model: Error: The clangbackend executable "C:\Qt\Tools\QtCreator\bin\clangbackend.exe" does not exist."

In the directory C:\Qt\Tools\QtCreator\bin\ there are only two clang*backend.exe files:

1) clangpchmanagerbackend.exe,

2) clangrefactoringbackend.exe.

When I disable the clang model, the syntax highlight works, but it can't resolve more sophisticated templates and the code completion does not work properly.
