Windows Service Installer - Access is Denied

Hi All,

I'm having trouble deploying a Windows Service installer (.NET 1.1) onto
some machines. It gets half way through the installer and gives me a dialog
box saying "Access Is Denied". When I click OK it does a rollback on the
install. The exact same installer has worked on both XP and Windows Server
2003 machines. It seems to have a problem on Small Business Server standard.


I am logged on as Administrator with Administrator privilages on all
machines. The following is written to the event log.

The description for Event ID ( 11001 ) in Source ( MsiInstaller ) cannot be
found. The local computer may not have the necessary registry information or
message DLL files to display messages from a remote computer. You may be able
to use the /AUXSOURCE= flag to retrieve this description; see Help and
Support for details. The following information is part of the event: Product:
LaserProUpdaterHost -- Error 1001. Access is denied.
, (NULL), (NULL), (NULL).

Please Help!
