Unable to Install iTunes 64 bit on Lenovo X1 with Windows 8.1

I get the error message in the screenshot attached when I try to install iTunes on my Lenovo (W 8.1). I havs done all the uninstalls (iTunes and all Apple and Bonjour programs and folders) and attempted reinstalls, and ever time I get this error message that Apple Mobile Device fails to start. I have installed Windows Media Pro for Windows 8, as aome have suggested but this makes no difference. I have also set permissions in system so Administrators hav full control, and I have even tried to install as Administrator. Appreciate any advice appreciated.
