I'm having a problem using the System.Net.WebC lient to download .exes from a web server. I'm testing everything on localhost, and the same code works fine with all other types of file. I even tried renaming the .exe extension of the file in question to .exe2, and that worked! Is there a security setting that doesn't let me download executables (the only error message I get is a timeout)? If so, is there a way to override it... I'm making a tool to update my software product over the Internet, and being able to download .exes is essential
Any suggestions, please?

Hello,
Thanks for your post. As I understand, the problem you are facing is it
fails to download .exe fils by using WebClient. Please correct me if there
is any misunderstandin g. I think more information is needed before moving
forward:
1. Could you download the file in Internet Explorer?
2. What's the error/exception message do you receive when it fails to
download?
3. Do you connect the Web Server via proxy?
I look forward to your reply. Have a nice day!

Check to see if the server allows you to download exe types. It may be
blocking downloads of executables.

Thanks for your help... in response to your queries
1) No, I couldn't download the file in Internet Explorer. The progress bar at the bottom-right moved extremely slowly, and finally an error page showed: "CGI Timeout: The specified CGI application exceeded the allowed time for processing. The server has deleted the process". For all other files, there was no problem. It can't be file size either, as the .exe is only 340kb, and as I said renaming the extension works fine
2) When it fails to download and error handling is disabled, I receive a "timeout" message, after a long time in which the program does not respond
3) I don't really know what proxy is, I'm afraid! I am connecting through a wireless network in my home, which I set up myself and has no security features that I know of. I've checked through the IE security settings, and have found no applicable restrictions
Hope this helps..
James.

And I've just found something else! Every time I try to download the file, either in Internet Explorer or my program, it starts (and does not close) a new process which is visible in the Task Manager. This process has the same name as my file ("TMI Management.exe" ). If I close this process before the usual timeout error occurs, I receive the following error: "CGI Error: The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: [blank]". It occurred to me that the computer may be trying to run, rather than download, the file. But I can't download notepad.exe either, so it's not specifically my application
Please advise
James.

Hello
Problem: I need to download files from an FTP site while moving very fast.
I expect connection problems during downloads. If a file is half downloaded and there is a connection glitch, then the file needs to be downloaded fully once again. Likewise, different actions have to be taken based on the error.
How to handle error cases using WebClient.DownloadFile? Or are there any other better APIs?
