OWC permissions on Windows Server 2003

[webmaster]

I'm having an issue with the Office (XP) Web Components (owc10.exe) on
our Windows Server 2003 machine. If it helps, FrontPage Server
Extensions 2002 are also enabled, and Excel XP is also installed on the
machine.

I'm trying to create an Excel file on the fly within a classic ASP
page. I keep getting this error:

==========
Server object error 'ASP 0178 : 80070005'

Server.CreateObject Access Error

/secure/webadmin/wpbec_backoffice_exportCustomersExec.asp, line 25

The call to Server.CreateObject failed while checking permissions.
Access is denied to this object.
==========

Line 25 looks like this:
set oExcel = Server.CreateObject("OWC.Spreadsheet")

I have given the destination folder read/write permission, and put an
empty .xls file in the folder with read/write permission too. I have no
clue what other permissions to set, or where to set them - can you shed
any light?

Thanks!

UPDATE: I followed the advice of the following KB article, and added
read/execute permission on msvbvm60.dll for IUSR_computername.

But I still get the same error.
