ngen compiled Class Progress Developer Studio for .NET

How to implement ngen.exe for compiled class in Progress Developer Studio for .NET?

I have read article in https://knowledgebase.progress.com/articles/Article/000039846 and

https://documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/pdsoe/.net-assemblies-and-the-visual-designer.html

and tried this syntax with Command Prompt run as admin :

    cd C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\
    ngen.exe install C:\OpenEdge11.6\bin\Progress.NetUI.dll

but it returns :

    C:\Windows\Microsoft.NET\Framework\v4.0.30319>ngen.exe install C:\OpenEdge11.6\bin\Progress.NetUI.dll
    Microsoft (R) CLR Native Image Generator - Version 4.6.1590.0

    Failed to load dependency Progress.Messages of assembly Progress.NetUI,

    following error : The system cannot find the file specified. (Exception 
    from HRESULT: 0x80070002)

    the file specified.. If this assembly is found during runtime of an 
    application, then the native image currently being generated will not be 
    used.

Does it works? or did I miss something in ngen syntax?
