Software Deployment

I have created a deployment package for Office 2003 which I have slipstreamed SP2 into but I have discovered that one feature being Mail Merge does not work correctly as when selecting an excel document (.xls) it instantly closes Word, no errors and nothing is reported to the event log. If the user selects either a .csv or .mdb the mail merge works fine, this issue occurs if you are either a standard or administrative user.
Testing I have conducted:
1. Create vanilla office 2003 package apply same mst, mail merge works fine.
2. Install office manually and apply sp2, mail merge works fine.

SP2 Slip Stream Process Used:
To slipstream the SP into the installation point, you have to extract the
files from the SP exe to get the msp files out of it. You will need the
FullFile (i.e. administrative) version of the patch to do this. The msp
files in the archive are MAINSP2ff.msp, OWC11SP2ff.msp, and
OWC102003SP2ff.msp. They can be extracted by opening the archive in WinZip
or by running the archive with the appropriate switches. From the command
line, use ArchiveName /? to get the list of options.
Once you have the msp files, use the following command lines to incorporate
them into the install point.
msiexec /a <path>\Pro11.msi /p <path>\MAINSP2ff.msp SHORTFILENAMES=1 /qb-
msiexec /a <path>\OWC11.msi /p <path>\OWC11SP2ff.msp SHORTFILENAMES=1 /qb-

If anyone has had this issue or could shed some light on the issue that would be great.
