Windows 7 WUG 12.4 on Windows2008 R2 with SQL Expr
 

Hi guys,Windows 7,
I'm struggling to put in WUG 12.four on Windows2008 R2 (64-bit) with SQL Express 2008 R2 in virtualisation environment (HYPER-V). From can see that SQL 2008 is supported since version 12.3.
I'm starting the installation,Microsoft Office 2010 Key, selecting existing SQL server with Windows Authentication,Office 2007 Key, installation continues and then setup still tries to initialise SQL Server 2005 Express Edition setup.... It fails with the error that SQL Server 2005 Express Edition 32-bit cannot be run in 64-bit environment.
Is there any way how I can setup the database manually or accomplish the installation without installing SQL Express 2005 ?
Thanks in advance.
John.
