title: What is "unknown software exception (0xc00000fd)" error and how to avoid it?
body: <p>I have created an AHK script named code_2, compiled it and placed it into my Startup folder so that it would automatically start running each time I turn on the computer.</p>
  
  <p>The script checks a website for new updates and whenever an update on the website is detected, it downloads those updates using UrlDownloadToFile.</p>
  
  <p>At first the script seemed to work fine, but recently I started receiving the following messages from my computer after my script has been running for about 15 minutes:</p>
  
  <blockquote>
    <p>C:\Documents and Settings\Administrator\「開始」功能表\程式集\啟動\code_2.exe:
    code_2.exe - 應用程式錯誤</p>
    
    <p>應用程式發生例外 unknown software exception (0xc00000fd) 於位置 0x7c92eddc。</p>
    
    <p>請按 [確定] 終止程式</p>
    
    <p>請按 [取消] 進行程式偵錯</p>
  </blockquote>
  
  <p>Any idea what this message is all about? (Sorry for the Chinese here, but I'd think that if you know this message by its number, you should be familiar with the contents.)</p>
  
  <p>Anyway, here is the translated message:</p>
  
  <blockquote>
    <h3>C:\Documents and Settings\Administrator\Start Menu\Programs\Startup\code_2.exe: code_2.exe - Application Error</h3>
    
    <p>The exception unknown software exception (0xc00000fd) occurred in the application at location 0x7c92eddc.</p>
    
    <p>Click on OK to terminate the program<br>
    Click on CANCEL to debug the program</p>
