Excel.Quit() failing when using Excel.exe through a non admin user

Question

Hello Folks,

I have just migrated Office 2013 to Office 2021 in my machine.

I am using the Office application through the COM model, where I create new Excel.Application() and then export it to a fixed XPs format and then close the excel application using Excel.Quit().

Excel.Quit() works fine when I run my application through Admin user.

But when I use a non - admin user which is less privileged the Excel.Quit() complains by throwing a :-

System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x800AC472

   at Microsoft.Office.Interop.Excel.ApplicationClass.Quit()

Answer 1

Office requires full admin rights
