running word as a windows service on vista

[Andy Fish]

Hi,

I was wondering if anyone has had any luck calling word using OLE from a
windows service on vista.

I am using .Net 2.0 and office 2007. My current code has been very reliable
on 2000, XP and 2003 Server with the service running as LocalSystem but I
can't get it to run on vista

it seems to fire up word ok but when I call Documents.Open(...) it returns
null every time. I have tried running the service as a normal windows user
account (with administrator privileges) but that doesn't help.

any hints much appreciated (except "don't run word as a service")

Andy
