com excel virker ikke på windows-server 2003

Hej
Jeg har lavet en excel-generator som virker fint lokalt på maskinen men ikke på webserveren (windows 2003 server).


Efter at have googlet mig frem så jeg at windows-serveren kræver at officepakken bliver installeret. Dette har jeg gjort (og brugte en licens på.... )


Jeg fik efterfølgende fejlen:
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005

Jeg har givet adgang for excel-mappen på serveren. Og fejlen er der ikke mere. Til gengæld for der ikke er nogen fejlmedd. popper excel-arket ikke frem. Kan nogen hjælpe mig med dette?
