Hi,
When I try to install .NET framework3.5SP1 on a win2k8 server running SQL 2008, I get the message "Setup error" in the install window. I am using the "dotnetfx35.exe" file downloaded from the Microsoft site at the link below:

I arrived in this position of needing to reinstall .NET framework3.5SP1 after I ran the .NET Cleanup Tool on all versions of .NET Framework on the server, in an attempt to fix an issue where some .NET Framework updates fail to install.
It seems .NET Framework 3.0SP2 and 4.5.1 install fine on the server. It is only 3.5SP1 that fails, and that is the version required by SQL Server 2008.
Any helpful advice would be very much appreciated. Thank you.
