• Hi,

  I’m using Visual Studio 2017 Community edition with Windows 10 and I can’t seem to create a reference to Microsoft.Office.Interop.Excel which I need in order to be able to use C# to create a spreadsheet that will open up in Excel.   Is this not available
  in the community edition or is there something else I am supposed to use?

  Thanks.

  You should post to the above forum.

• Hello,

  You should be able to «add reference», select «Assemblies», press the «Browse» button, traverse to a path along this line (most likely close to your machine but slightly different)

  C:Program Files (x86)Microsoft Visual Studio 14.0Visual Studio Tools for OfficePIAOffice15

  Then you should see to select

• Had the same question, finally figured it out.

  1. Go to the Visual Studio Installer

  

  2. In the Installer, click the Modify Button:

  

  3. Go to the Individual Components tab and click: Visual Studio Tools for Office (VSTO)

  

  4. Click Modify and let it install.

  5. Open your Visual Studio project, go to Assemblies, in the search box type in office, and choose: Microsoft.Office.Interop.Excel.

  

  6. On top of the module, add: Imports Microsoft.Office.Interop.Excel

• Hi steven,

  I don’t have Office 2010 and Visual Studio 2017 in the same machine.

  This is a combination of Office 2016 and Visual Studio 2017.
      C:Program Files (x86)Microsoft Visual Studio 14.0Visual Studio Tools for OfficePIAOffice15
      

  Please search it according to your environment.

• Hi ,

  Our forum focus on the Microsoft Teams, based on your description, the problem is related to MS Visual Studio, so I moved this thread to the Visual Studio Tools for Office forum.

  Thanks for your understanding.

• Hello Steven2005A,

  Does AshidacchiH’s suggestion work for you?

  If it does, please mark helpful reply to close the thread.

  If not, please follow up to let know the current state of the issue.

  Besides, you could also try to check if visual studio could get the API from

  Assemblies->Entensions->Microsoft.Office.Interop.Excel

  

  Or form

  Com->Type Libraries->Microsoft Excel XX.0 Object Library

• hi Terry,

  Thank you for your reply.

  My question is why cannot I see Microsoft.Office.Interop.Excel under Assemblies-> Extensions-> ?

  I work in a team environment, and others can see it and we are using the same version of windows/VS/Office

  

• Hello Steven2005A,

  I would suggest you try to go to control panel to repair or re-install the office.

  Best Regards,
