I have a crawling program that fetches urls to parse the html and came across an unusual error since I started this. For a specific set of urls from a site when fetching using HTTPWebRequest and HTTPWebResponse I get the error The remote server returned an error: (404) Not Found This is unusual since it works when pasting it in my browser. Not sure if code is needed to posted but let me know if so.

I'm trying to send some data onto a server. The data is an XML in form of string and and image encoded to base64.The problem is that the server says '404 Not Found', just as if I had an incorrect URL, but my URL is 100% correct. I can get data from the server using GET, but when I try to POST it doesn't work.I checked it in Fiddler and it first gets z 401 error (not logged in) and then the 404 error, which results in an exception.Can anybody please have a look at the below code and tell me if there is something I'm doing wrong?

I getting an error which is:
Error 1 Task failed because "AL.exe" was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for "AL.exe" in the "bin" subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SDKsWindowsv6.0A. You may be able to solve the problem by doing one of the following:
1) Install the Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5.
2) Install Visual Studio 2008.
3) Manually set the above registry key to the correct location.
4) Pass the correct location into the "ToolPath" parameter of the task. OutlookBar v2 2005.

I have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:
If System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "license.dat") = False Then
File dialog code goes here

I'm trying to connect to a remote server (from our customer) via HttpWebRequest.GetResponse but at the login page i'm always getting an exception: "The remote server returned an error: (500) Internal Server Error." In the response stream i see that i was redirected to the error-page. The code worked so far(HTTP status 200) with the old ASP-website but they'll migrate to ASP.NET soon. There's no error if i browse to the URL manually. This is the (reduced) code:
