I had to reinstall my Windows XP Professional on my Dell Computer. I then update to Service pak 3. I installed my Microsoft Office 2007. However when tried to install the second disk. I get the following message: Setup failed to install required component Microsoft SQL Server Express (MMSMLBIZ) Microsoft Office Proesssional 2007 CD 2 cannot continue. See C:\Program Files\Microsoft QL Server\90\Setup Bootstrap\LOG\Summary.txt for more detail. Error 29506 Looks like it trying to get permission to open a file. I have administrator authority.
