I have slipstreamed Office 2003 with SP3
I can tell what worked for me. I got all the way to "monnezza" post except the InfoPath hotfix would not slipstream with SP3.
So I created the slipstream like the website http://www.petri.co....ipstreaming.htm
says to with SP2.
Got the same error message "insert disk”, when trying to install from CD. Tried to slipstream InfoPath hotfix got an error message "The upgrade patch cannot be install by the Windows Installer" I really didn't think to get a screen shot but I can make the error message again and post it if you want. I then disregarded up to the part "run Orca" in "monnezza" post. Adjust the two files in Orca. Burned a CD with UltraISO.
Tested the new CD on the first laptop I tried to receive the error message "insert a disk", and the install then went through. Tested on a W2K3 server, that never had an install of Office 2003. Just to make sure and both worked.
I was not going to post at first but then I thought better, as I lay down to start the next day I was complied to post (I guess you can call it guilt), I find myself writing to tell you how I found a work around. The key to my success was trail & error. I just need to find the work around a lot quicker next time. I also found out why I love my job
Thanks to all who have posted about this.
