Cygwin 1.7.1 install halting on Windows 7

[Durwin]

I am still in need of help.  The post install scripts are not successful. 
During some install attempts, the install completes but the log file
says the scripts terminated abnormally.

*  I did set setup.exe to run as administrator.
* The path 'c:\cygwin\bin' was left in through all install attempts.

I am at a loss.  If there are any ideas, I welcome them.

Summary:
New Alienware laptop with Dell installed Windows 7.
What other information would be important at this stage?  I included a
chgcheck from one installation.

Many thanks,

Durwin
