I had this same issue too, Make sure Windows is updated and if needed download a fresh copy of iTunes from, http://itunes.com.
If it continues, try these steps.
Try repairing Apple Software Update from the programs & features control panel, and then try to update iTunes again. You may also want to temporarily disable any anti-virus software.
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. When reinstalling right click on the downloaded setup file and use run as administrator. It may also help to pre-install the Microsoft Visual C++ 2005 Redistributable.
Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, or want to revert to an older version if the current one won't work properly for you at the moment.
Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.
