Unable to update .net framework, help please!

[Shadowssong]

Hey guys, I'm working on my assembly homework and I've been trying to do it via xspim but for some reason it doesn't run my code properly so I am trying to use pcspim. When I start up pcspim it says you need .net framework 3.5 installed, I click to install .net framework and it downloads and starts installing and then I get this error:

"An error occurred while installing system components for PCSpim. Setup cannot continue until all system components have been successfully installs.
DETAILS:

Component .NET Framework 3.5 has failed to install with the following error message:
"Fatal error during installation. "

The following components failed to install:
- .NET Framework 3.5

See the setup log file located at 'C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\VSD8.tmp\install.log' for more information."

The follow is the contents of the install.log file.

I am running windows xp sp3.
Can anyone help? I apparently really need to us PCSpim instead of xspim because it runs my code properly (I don't get this part either). Please please help, many thanks in advance!

Edit: Just thought I'd toss this in there. When I tried a different installer for .net 3.5
I got the windows send report/don't send report and this is what it said under what doe sthis report contain:

EventType : visualstudio8setup P1 : 35101
P2 : 3.5.30729.01_orcas_x86_net P3 : pr P4 : inst P5 : f
P6 : gencomp209 P7 : baseret_failure P8 : - P9 : 1603 P10 : -

Don't know if that helps, again thanks to any help.

Nevermind!!! I got spim working on linux, all i had to do was use the -mapped_io flag, therefore I have no use for pcspim, and therefore no use for updating .net framework. Thanks for lookin
