Install SQL 2008 R2 on Win 8 fails with Microsoft.SqlServer.Configuration.Sco.ScoException

Hello SQL Gurus

I'm trying to install SQL 2008 R2 on Win 8 Enterprise edition. I see other posts that I need to install SP1 or SP2 also, but 2008 R2 itself is failing with exception,Microsoft.SqlServer.Configuration.Sco.ScoException.

I looked at other posts, so I did "winmgmt /verifyrepository", it said, "WMI repository is consistent".

While install it gave the following error dialog box, Image may be NSFW.
Clik here to view.

And also here is the log file, any idea what could be happening?

Thanks Bhava
