How to install Microsoft.Office.Interop.Excel.dll for Dynamo via Revit2021? Office2007?

I used Revit2018 before and all was good. But recently i got Revit2021, and it causes problem with API scripts in Dynamo, using Microsoft.Office.Interop.Excel.dll. I have read that topic «Предупреждение: ошибка операции Data.ImportExcel. Не удалось загрузить файл или сборку Microsoft.Office.Interop.Excel... при запуске сценария Dynamo в Revit | Revit 2021 | Autodesk Knowledge Network but it was useless - i have Office2007 on my PC, and there is even no folders GAC_MSIL in C:\Windows\assembly\ . How can I solve that problem with Office2007?

Hope it helps

Thanks for help, but i have only Office2007 32bit, and i cannot get x64Office - it is our corporative solution. So it is still a question is it possible to install Microsoft.Office.Interop.Excel.dll for Revit2021 and 2007 Officeх32.
