Issue installing SQL 2014 CTP2

Good morning,

I am trying to install SQL 2014 CTP2 and am having a bit of an issue.  Having uninstalled 2014 CTP1, I attempted to install on my Windows 7 Professional (SP1) x64 laptop.

Any advice on this issue would be greatly appreciated.

The installation repeatedly gets to the same point and then hangs at "Install_SQLSupport_Cpu64_Action".  Reading the Detail.txt file in the C:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\Log\20131028_084421 folder, I see the following:

The worrying things here are the following:

(01) 2013-10-28 08:57:13 Slp: Sco: File 'G:\1033_ENU_LP\x64\setup\sqlsupport_msi\x64\SqlSupport.msi' does not exist

and then the infinite loop regarding the Win32 API.

I've had a look at the install media (a downloaded ISO) and found that the SQLSupport.msi does exist, however it is found here:

G:\1033_ENU_LP\x64\Setup\sqlsupport_msi\SQLSupport.msi

G:\1033_ENU_LP\x64\Setup\sqlsupport_msi\ 

The following steps will repro the issue: 

Installation: New SQL Stand-Alone insatllation or add features to an existing installation.
Edition : Evaluation
Accept Terms
Click Next on Install Rules
Setup Role: SQL Server Feature Installation
Instance Features:
database engine services: SQL Server replication, Full Text Semantic Extractions
Shared Features:
Client Tools Connectivity, Integration Services, Client Tools Backwards Compatibility, Client Tools SDK, Documentation Components, Management tools Complete

Click "Next"
Instance Configuration: Default Instance with Default Instance Name, Click Next
Server Configuration: Accept all defaults, Next
Database Engine Configuration: Mixed Mode, Specify SQL Server Administrators : Domain Group.  Continue with Next
Install

Any advice, or pointers would be greatly appreciated.

Regards,

Andy
