.NET Framework 3.5 SP1 install problem ---- Please Help

[John Monahan]

I hope somebody can help me out here.
I just got Expression Web V3. It tells me I don't have .NET Framework 3.5
SP1 installed.

When I download the .NET SP1 from MS it installs about half way then says
an error was detected and unwinds everything.

The error box says "see Error Log". What error log? where? When I click on
it, MS Visual Studio 2008, it comes up but has its own error box "file
cannot be opened because it is being used by another application".

Talk about frustrating!

I reinstalled/repaired .NET 3.5 it went fine -- at least no errors reported.

Besides Visual Studio 2008, I show
..NET Component Framework 1.0 SP3 developer
..NET Component Framework 2.0 SP2
..NET Component Framework 3.5
..NET Framework 3.5

Really could use some suggestions here as I just want to get Ex Web 3.0
going.
If this is not the best posing site please suggest an alternative

Followup...
I removed all .NET's, removed Visual Studio 2008 and reinstalled it. It put
..NET 3.5 back (only).
Still could not load .NET .SP1
Got the following error in the event viewer log (Windows logs,Setup):-
The Windows update "Update for Windows (KB948610)" could not be installed
because of an error: 2147956403 "The referenced assembly is not installed on
your system." (Command line: ""C:\Windows\system32\WUSA.exe"
"C:\Users\JOHNMO~1\AppData\Local\Temp\dotnetfx3530729.01\1033\dotnetmsp\x86\NetFX3.0-KB948610-v6001-x86.msu"
/quiet /norestart")

Any suggestions anybody

How did you remove NET Framework 3.5? Only classic Control
Panel>>Programs and Features? -it's not enough.Remove NET Framework 3.5
by using NET Framework Cleanup Tool by Aaron Stebner 'Aaron Stebner's
WebLog : What to do if other .NET Framework setup troubleshooting steps
do not help'
(http://blogs.msdn.com/astebner/archive/2005/10/11/479928.aspx)

Tried that. I removed all .NET listings and then ran the above program
twice. When I tried to install the .NET 3.5 + SP1 it proceeded as usual
about half way and then aborted. Same errot in System Error Log
(Command line: ""C:\Windows\system32\WUSA.exe"
"C:\Users\JOHNMO~1\AppData\Local\Temp\dotnetfx3530729.01\1033\dotnetmsp\x86\NetFX3.0-KB948610-v6001-x86.msu"

Thanks Flavius,
I gave up and want back to a 1 year old WHS backup and started from there. A
real pain to reconstruct everything but at least I think I am ready for W7.
