uninstalling quicktime

i cant seem to uninstall quicktime from my pc...its doing my head in! i
really want to put itunes on but it wont let me as i have a dodgy version of
quicktime which seems to be stuck there!

this is the message i get when i try to remove it.

the following file does not exist or is not a valid uninstallation log file.
c:\WINDOWS\system32\quicktime\uninstall.log

dont know what to do?? really want itunes back and be able to watch vids on
quicktime again!

can anyone help me with this???

cheers, dan
