old one is 9.0.2 and the new one is 11.0.1.dmg
new one is downloaded but I assume it won't let me acces it because the old version is still there...I bought my young daugther a newer ipod touch 4 and the old itunes doesn't "recognize" it, so I assume I needed a newer version
Thanks in advance for your advice
iTunes is not installing because its incompatible with your OS. When installing the correct version the new version will update the older version, there is no need to uninstall first.
The last version of iTunes compatible with OSX 10.4 is iTunes 9.2.1
You can down load iTunes 9.2.1 here:
