ASP.NET 2.0 AJAX Extensions 1.0 install problem

Every time I try to install I get the following error:

ASP.NET 2.0 AJAX Extensions 1.0 Setup Wizard ended prematurely.

Microsoft ASP.NET 2.0 AJAX Extensions 1.0 Setup Wizard
ended prematurely because of an error. Your system has
not been modified. To install this program at a later time, run
the Setup Wizard again.

Click the Finish button to exit the Setup Wizard.

I have never had a previous copy installed. I am running Windows XP Professional Service Pack 2, Visual Studio Professional 2005, Framework 2.0.

I have every update installed and no matter what I do I keep getting the same error message.

Any Ideas?

The install fails with:

ExecNetFx: Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
ExecNetFx: Error 0x8007006d: failed to allocate output string
ExecNetFx: Error 0xffffffff: Command line returned an error.
ExecNetFx: Error 0xffffffff: failed to execute Ngen command: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exe install "System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

Problem Solved!

This is a very bad way to fix the problem but it worked.

I ran the install and hit cancel after the files had all been copied. At this point it asked me if I really wanted to cancel. Before I answered, I copied the folder "Program Files\Microsoft ASP.NET" to another location on my hard drive". I then answered yes, and it deleted every thing.

I then copied the folder "Program Files\Microsoft ASP.NET" back.

At this point I used Control Panel->Administrative Tools->Microsoft .NET Framework 2.0 Configuration to add the three .dll files in the folder to the assembly cache.

I ran the install package and it worked.

Excellent solution. I was trying hard to ind a way to the same problem. This solution worked fine with me too.

Great job.
