I am unable to install the newest update for itunes and quicktime because of a bonjour error about path not being located

I have windows 7 and I have been trying to install the newest update for itunes and quicktime but I keep receiving the same Bonjour error. I even tried to do it manually and no luck. I also tried to unistall bonjour but it would not even allow me to unistall it either. No matter what I do I get the same error listed below:

The path C:\users\owner\appdata\local\apple\apple software update\bonjour64.msi cannot be found. verify that you have access to this location and try again or try to find the installation package "bonjour64.msi" in a folder from which you can install the product bonjour.

I would greatly appreciate any help because this appears whether i am trying to install the updates or remove bonjour to reinstall. I am stuck.

Thank You in advance!!!
