    Install error: Could not load file or assembly 'System.Web.Extensions...

    OK, I'm following the instructions here - 
    http://umbraco.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=33743#DownloadId=95707
    - to install Umbraco locally on my Vista PC.

    I created a new website in IIS using port 81. When I go to http://localhost:81/ to start up the "web-based configuration wizard" I get the error below. I've googled this error and it appears related to Ajax. However, I have .NET 3.5 SP1 installed so I should already have everything I need as far as AJAX, right?

    I'm a newbie to all this - IIS, etc.- so please be specific in your replies about what I might do to fix this. 

     

    Server Error in '/' Application.

    Hi tesuji

    Try installing the ASP.NET AJAX 1.0, right here: http://www.microsoft.com/downloads/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en

    Sometimes this is not installet, so give it a shot.

    OK, I got the setup wizard to open. THANKS

     

    I installed Ajax using your link.

    Then I got another error. CS0016: Could not write to output file ‘c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files… ‘Access is denied.’

    I fixed this by giving some more permissions as described here: http://www.jayceooi.com/2008/09/23/cs0016-could-not-write-to-output-file-cwindowsmicrosoftnetframeworkv2050727temporary-aspnet-files-access-is-denied/
