Vista - Problem With Visual Basic 2008

I am in a high school programt that uses Visual Basic 2008. Every time I try to Debug it, an error message appear every time.

The message is:
Visual Studio cannot start debugging because the debug target
'C:\Users\EragonX\AppData\Local\Temporary
projects/WindowsApplication1\bin\debug\WindowsApplication1.exe'
is missing. Please build project and retry, or set the Output path and
AssemblyName Properties appopriatly to point at the correct location
for target assembley

The error is: Error 1 The specified task executable location "C:\Windows\Microsoft.NET\Framework\v3.5\Vbc.exe" is invalid.

What is Wrong?

I tried Re-installing it 3 times allready!

If anyone want the screenshot for the error, I will e-mail you the screenshot. Just give me your e-mail adress and I will send it to you.

Hi Eargon,

I think you need the Windows SDK with .net 3.5...(It says Server 2008 but this is the also the Vista SDK) You will also need Visual Studio SP1, also make sure you didnt set any irregular project properties

Download details: Windows SDK for Windows Server 2008 and .NET Framework version 3.5

Download details: Visual Studio 2008 Service Pack 1

Thats all you should need

Oh.... That brings me to my second major problem...

My computer blocks all automatic updates for some reason....

Both the SDK and the SP1 require internet, but my computer blocks them

I can't update my ad-aware OR my AVG free, or any program that needs automatic update or connection with the internet.
