After you have uninstalled Quicktime, go into your \Windows\System32 directory and make sure the Quicktime.qts is deleted.
Next, what version of Java are you using? Perhaps, you should download a more recent version.
Essentially, what I make of this error is that a pretimed window is to be opened and if it fails, to shut the process down. Quicktime was created to work on Macs not Windows. Windows MFC won't allow for those kinds of windows any longer. Had you inadvertantly downloaded the Mac installer previously and tried to run it, then tried to install the Windows version? Or had the software from the ipod tried to do so?
