Microsoft Windows Installer

I current have problems installing 2 programs. I think it Microsoft Windows
Installer.
One program is Microsoft Outlook. When I start Outlook the Windows installer
start and says its gathering information, but seem to die and outlook start.
This happens every time I start. When I look at the firstrun.log for Outlook
I see the following
*** Starting First Run (02-04-2008 21:31:53) ***
....HrPreSplashFirstRun called.
....HrPreLogFirstRun called.
....HrPostLogFirstRun called.
...... FCheckFirstRunStatus failed reading machine value "17019"!
....deleting WAB4/UseOutlook because we're using MAPI.
....writing UUID to HKCU.
....setting Primary Client to Outlook.
*** Ending First Run (02-04-2008 21:31:58) ***

Also I am having problem installing Norton SystemWorks. When I contacted
Symantec tech support they said that the problem I am have can be caused when
the Windows installer fails

Is there any information on how Vista Windows installer (program) work. Is
there installer log file.
HELP!!!
