Check if you are using any other virtualization software like Oracle/Sun's Virtual box or VMware. If you are using another virtualization software, then uninstall it, reboot & install virtual pc (KB958559), Should install fine. hope this below link will be helpfull.. http://social.technet.microsoft.com/Forums/en/w7itprovirt/thread/00c74bd9-da7b-4acb-ae5a-7112377bc7e2Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi, I suggest running System Update Readiness Tool first. http://www.microsoft.com/downloads/en/details.aspx?FamilyID=914fbc5b-1fba-4bae-a7c3-d2c47c6fcffc After that, disable your security software and install KB958559 again to check the result. http://www.microsoft.com/download/en/details.aspx?id=3702 If the issue persists, try to check disk for testing. 1. Open CMD with administrator privileges. 2. type command: chkdsk /f /r Best Regards, Niki Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
