I can't install itunes because an old version quicktime won't uninstall. Tried heaps of things of the net but no luck including all of Apple support recommendations. When I try to install quicktime it says it can't find the quicktime.MSI and when I point it to the msi . Ite says that it is and invalid msi file.
sorry tried this no go in fact I have tried several registry cleaners with no luck
If you know how, you can manually remove all entries regarding quicktime. Have you ever edited a registry manually before?
