Don't know if you got this figured out yet but you need to go to the folder properties for the folders you were being denied access too such as C:\Program Files (x86)\Common Files\Unitronics and then Right Click, go to properties and then the security tab and then enable read/write access for all the different users. Even if you installed the program as an administrator, it doesn't always give you the correct read/write access permissions, you need to assign them yourself
