Additional Information

For additional information on troubleshooting iTunes installation see Trouble installing iTunes or QuickTime software in Windows.

If you have the correct  system requirements for installing iTunes, this message may indicate that the installer file was damaged during download, or the download was not complete. This can be caused by having a pop-up blocker turned on. Before downloading iTunes again, turn off any pop-up blockers (the built-in pop-up blocker settings in Internet Explorer are in the Internet Options control panel under the Privacy tab).
