Hi friend!
The default settings of Internet Explorer on Windows 2008 cause this problem.
1.On the menu bar of Internet Explorer, choose Tools > Internet Options (If the menu bar is unavailable, press Alt to display it.).
2.In the Internet Options dialog box, click the Security tab.
3.On the Security tab page, click Custom level....
4.In the Security Settings - Internet Zone dialog box, set ActiveX controls and plug-ins to Enable.
Thanks!
