Hog 3PC was really only supported through Windows 7. I know people have generally got it to work with Win 8, but they would need add their work-around here.
Off the top of my head, make sure to completely remove any previous versions of Hog PC. www2.highend.com/support/controllers/documents/Uninstalling%20or%20Upgrading%20PreSP3.pdf
Disable the Windows UAC; www2.highend.com/support/controllers/documents/WindowsUAC.pdf
