Revert to Win7 iTunes .msi issue
Over the last two days I've reverted two of my 4 PCs back to Win7 and experienced the same problem with iTunes. After reverting (both are Win Pro 64-bit) I was unable to either repair, update, or remove iTunes. Windows could not locate the iTunes6464.msi, usually in an Apple Software Update folder. Is suspect that the Win10 upgrade process moved the msi file to a temp folder and then writes the path to the registry. The reversion process appears does not update the registry and does restore the msi file to its original location leaving you to deal with "where the heck is the iTunes6464.msi" issue. If you are lucky to have made a back up before the upgrade you restore it and point the installer to the new location. Note that is that the msi version must match your installed iTunes. So word to the wise, if you revert back to Win7, uninstall iTunes and it's associated support programs (see http://support.apple.com/en-us/HT204275) before you downgrade and then install a fresh copy in Win 7. FYI, missing Apple msi files are a know issue that Apple has never fully addressed.
