System.Runtime.InteropServices.COMException (0x80040154):

Question

My 64 bit server which is running 32 bit office,

what my application does is get the data and create a excel file in server.

I am getting this error :

System.Runtime.InteropServices.COMException (0x80040154):

Retrieving the COM class factory for component with CLSID {xxx-xx-xxxx}

failed due to the following error: 80040154.

I checked in GAC in my server, its missing MIcrosoft.Office.Interop.Excel.

How do i fix this issue?
