If you are running McAfee as your antivirus program, try disabling the Access Protection or disable McAfee altogether. After doing so, install all of your Windows Updates, reboot your machine, and uninstall/re-install Studio One. Make sure that McAfee is disabled through all of this. Here is an article from McAfee that illustrates the problem, should this be what you are experiencing.
