it appears that all of the log files show detailed log information for the original named instance install
ComputerName\SQLExpress
However none of the log files including the summary.txt file appear to show any data on the attempt to install a second named instance.
computerName\SecondInstanc
So unfortunately they appear to have no data in them in regards to the issue.
However, I am closing the question, because after reading a great deal of help on sql express 05 i have decided to use the default named instanct sqlExpress05 and will award points for the good advice.
thank you

To read a SQL Server Setup log file
Open Windows Explorer and navigate to:
%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\LOG
Open the Summary.txt file. Look through it for error messages.
If you do not find information in the Summary.txt file that tells you what failed, open the SQLSetup[xxxx].cab file in the same root directory.
If this .cab file does not exist, open up the CORE log file from:
%ProgramFiles%\Microsoft SQL Server\90\Setup Bootstrap\LOG\Files
Look at the most recently modified core log: SQLSetup[xxxx]_[ComputerNa
If a component failed during the installation progress dialog, open the log file SQLSetup[xxxx]_[ComputerNa

also you can check the system configuration by the System Configuration Checker
