in reply to use Win32::IEAutomation;

Try this HTML. The text type works but the file doesn't which suggests the problem is not with Perl but with security features in IE introduced since 2006 that prevents the value being preset.

<html>
<head>
</head>
<body>
<INPUT TYPE="TEXT" NAME="upfile1" VALUE="c:\qctool.jar"/>
<BR>
<INPUT TYPE="FILE" NAME="upfile2" VALUE="c:\qctool.jar"/>
</body>
</html>
