I'm getting an odd problem when I try to download files from the internet. Typically the file appears to download correctly, but when I try to run it, I get an error message saying

is not a valid win32 application.

On inspection the size of the file is not correct.

Here is an example that I tried 4 times. Only on the 4th attempt did it download correctly:

The file I happen to be trying to download is the .net framework 1.1, but I've had it happen with others. I am using Firefox, but I get the same problem with IE.

Do you go through a proxy? Can you try "wget" or any download manager? – LatinSuD Jun 6 '11 at 12:54
    
No. I don't go through proxy. Would really like to understand why it's happening. – Urbycoz Jun 6 '11 at 14:52

Your picture shows different file sizes -- implies the download failed at times.
Consider using a download manager like DownthemAll

Any idea what could be causing it? – Urbycoz Jun 6 '11 at 14:52
    
network timeouts is one guess. – nik Jun 6 '11 at 16:31
    
I have DownThemAll installed, and I now get this message for every file I download with it. Firefox's default Download Manager works fine though. – travis May 4 '12 at 16:41
