After many uninstalls and reinstalls of Microsoft Redistributable and many restarts of my computer I still manage to get the same error that states "C:\Program Files (x86)\VEGAS\Shared Plug-Ins\Audio_x64\sfppack1_x64.dll failed to register. HRESULT -2147010895. Contact your support personnel"

When checking my registration of my Vegas Pro serial number it says that it has already been registered so I don't believe that my registration not being active is the problem. If anyone knows a fix for this error let me know.
