Currency converter exercise problem

I have added “Use Excel file” and “Read csv” and configured them as specified in the video. After pressing the Run button the system gave the message (I have translated it from Russian):

It is not to bring COM-object of type “Microsoft.Office.Interop.Excel.ApplicationClass” to the interface type “Microsoft.Office.Interop.Excel._Application”. Error operation completion, as the call of QueryInterface COM-component for the interface with IID “{000208D5-0000-0000-C000-000000000046}” returned the following error: Interface is not registered (Exception from HRESULT: 0x80040155)

After that I have removed MS Office 365 from my computer, rebooted it and installed MS Office 365 from my page on the site.
The error has not disappeared.
How can I fix it?
Best regards,

Is it licenced MS office software? If not try to activate the account.

Yes. I have licensed MS office. I have checked through regedit that correct path is indicated in the floder 0 to Excel.exe. I also see that when I start Excel.exe it loads UiPath.Inegration.ExcelAddin. But as I have mentioned in the first message the problem remains. But in the log of Excel Addin Install it also specify the issue. (while StudioX said that ExcelAddin was added sucessfully).
