I don't know if LZ has installed Office XP PIAs on the server. If it has not installed Office, it must be installed on the machine.

I also encountered this problem, Retrieving the COM class factory for component with CLSID {0002E55D-0000-0000-C000-000000000046} failed due to the following error: 80040154.
Has not been resolved, is studying

I studied for a day and finally solved it: copy the'Microsoft.Office.Interop.Owc11 under VS to the bin directory of the server inside.
