SQL Server 2008 R2 on Windows Server 2008 R2 Purgatory

I’ve spent a day trying to get SQL Server 2008 R2 Installed on Windows Server 2008 R2. Not just on one box, but on several (including Windows 7). What should be a trivial matter gets very obtuse.


The boxes have VS 2010 installed, and .Net 3.5 SP1.


When I run setup it, I get this lovely message:



Using the .NET Verification Utility confirms the installation



So I have to install that which is installed. Googling did not find a solution and a lot of folks suffering the same problem. I had encountered this issue before and put it on the back burner (not upgrading to R2) after spending a day or two trying to find a solution without success.


To add further mystery – I see that some R2 features are installed…


Looking at the Install Log (in the %tmp% folder), reveals:

09:16:23.067 Attempting to find media for .Net version 3.5
09:16:23.067 Error: Cannot determine file version of .Net redist: 0x80004005
09:16:25.984 .Net version 3.5 installation failed, so setup will close. Error code: 0x80004005


Currently still looking for a solution (tried most of those suggested on the web)

  • Uninstalling all features and roles then do 3.51 only: failed.
  • Uninstalling all prior versions of SQL Server: failed
  1. Success finally by downloading the latest trial version and then copy all of the child folders to the old image. It was a data corruption issue.


  1. I've found the problem file, that being ../redist/DotNetFrameworks/dotNetFx35setup.exe. I've tested that you can replace the file with a downloaded version of the .Net Framework 3.5 SP1 from the Microsoft site. Just replace the appropriate redist folder (or even just dotNetFx35setup.exe file) for the server that you are installing SQL Server 2008 on. That is on a 32bit machine replace x86, Intel 64bit processor replace x64, etc..
