So for I have been unsuccessful at getting the 11gR2 Client to install on 64-bit Windows Server 2008 R2

I've tried all the suggestions from other posts...

Windows Update is current
McAfee Virus completely turned off.
Firewall disabled.
Logged on as local Administrator.
Running setup.exe from CMD prompt using "Run as Administrator"
Installation files located in C:\Temp
"Everyone" has "Full Control" on c:\temp
Tried "setup.exe -ignoreSysPrereqs"

When I run setup.exe, I see setup.exe and unzip.exe running in Task Manager for a moment, then both exit...nothing happens after that.
If I look in %Temp%, I can find the temp install files and a file "InstallActions<date><time>" with the following content:
-------------
Using paramFile: C:\temp\install\oraparam.ini


Checking monitor: must be configured to display at least 256 colors. Actual 65536 Passed

The commandline for unzip:
C:\temp\install\unzip -qqqo ..\stage\Components\oracle.jdk\1.5.0.17.04\1\DataFiles/"*.jar" -d "C:\Users\ADMINI~1\AppData\Local\Temp\OraInstall2010-05-14_08-19-59AM"
-------------

That's it....nothing else. Universal Installer never starts.

I have also tried executing "oui.exe" in the install directory with the same result

Any suggestions are much appreciated.
