title: Installscript CopyFile Function Error
body: <p>I am trying to copy a file using Installscript copy file function:
  bRet=CopyFile( szUnattendIni, szStatusFile );  </p>
  
  <p>where the file referred by szUnattendIni is passed as command line argument.
  When I pass this file from commandline using double quotes, bRet returns an error saying "System cannot find the file specified"...but when I pass the same name without double quotes, it works fine.</p>
  
  <p>I tried adding a check before copying to verify whether source file exists using:
      if(Is( FILE_EXISTS,szUnattendIni)) then
         MessageBox("File Exists",INFORMATION);
      endif;</p>
  
  <p>In both the cases, the message box is displayed saying the file exists.
  I want to support paths with directory name containing spaces for which double quotes is required. But I am not able to. How can I fix this problem.</p>
