Hello. I am Korean Woowon.
While developing with webform, I couldn't solve it, so I left a question like this.
I keep getting the same error message when declaring the Microsoft.Office.Interop.Excel.Application interface object.
I searched all the documents through Googling and applied the solution, but I couldn't solve it.
error message -> "Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070520 A specified logon session does not exist. It may already have been terminated."
please tell me the solution.. I think I will get cancer because of this

As tag “office-excel-itpro" is related to general issue of Excel desktop app, but yous issue is more related to code which is out of our support scope. I would remove it,
Thanks for your understanding. -
