Hello,

I am trying to install SQL Server 2008 R2 but I am getting an error:

TITLE: Microsoft SQL Server 2008 R2 Setup
------------------------------
The following error has occurred:
Source file not found: C:\Users\dominiqued\Desktop\SQL 2008 R2 Ent Ed\x64\setup\sql_engine_core_inst_msi\PFiles\SqlServr\MSSQL.X\MSSQL\Binn\wakslhwn.ldf.  Verify that the file exists and that you can access it.

------------------------------
BUTTONS:
OK
------------------------------

Not sure what to do, I try after uninstalling the previous failed installation but still the same error..
Where is this file? It is even not on the download from the Microsoft web site ... (:

I was able to find the file in SQL Server 2008 Ent SP1 but after it is the file 32veaiq8.mdf which is missing...

Where could I get a correct and complete version of SQL Server 2008 R2?

Thanks,
Dom
