Folder GAC_MSIL in the assembly folder

Question

I have a project C# it works stably on one of the computers under WinServer2012
I want to transfer the C # project to another computer under win10(64x)
there is a problem, the project does not work on win10 as it uses components Microsoft.Office.Interop.Outlook.dll
I checked that on WinServer2012 the assembly folder contains the GAC_MSIL folder in which the Microsoft.Office.Interop.Outlook.dll library is located and the project uses it.
But the win10 (64x) GAC_MSIL folder is missing, and the assembly folder contains only a list of libraries.
I downloaded https://www.microsoft.com/en-us/download/confirmation.aspx?id=3508 and installed the package but the GAC_MSIL folder did not appear.
Tell me what to install so that the GAC_MSIL folder appears in the assembly folder?

Hi,

Welcome to MSDN forum.

Did you install office/office tools for visual studio on win10?

In the solution explorer->add reference->look for it under COM.

Besides, Visual Studio installs these copies of Primary interop assemblies to the following locations on the development computer:

%ProgramFiles%\Microsoft Visual Studio xx.0\Visual Studio Tools for Office\PIA\Office14

(or %ProgramFiles(x86)%\Microsoft Visual Studio xx.0\Visual Studio Tools for Office\PIA\Office14 on 64-bit operating systems)

%ProgramFiles%\Microsoft Visual Studio xx.0\Visual Studio Tools for Office\PIA\Office15

(or %ProgramFiles(x86)%\Microsoft Visual Studio xx.0\Visual Studio Tools for Office\PIA\Office15 on 64-bit operating systems)

visual studio 2017: %ProgramFiles(x86)%\Microsoft Visual Studio\Shared\Visual Studio Tools for Office\PIA\Office1x
