I cannot uninstall itunes due to a missing .msi file
In trying to update my IPhone 4S to OS 6, iTunes tells me I must be updated to the newest version of iTunes. Unpon updating, iTunes tells me I cannot update due to a missing .msi file. Various outlets suggest uninstalling and reinstalling iTunes. I have followed suggested steps to uninstall iTunes. No matter how many different ways I try, my computer tells me that I am unable to uninstall because of a missing iTunes.msi file. I can't find this faile anywhere on my computer. I cannot find any other way to uninstall iTunes. Any suggestions?
iPhone 4S, iOS 6, iTunes
