Failed to install DaVinci Control Panels

I first installed Da Vinci Resolve and including the DaVinci Control Panels on my Hard Drive "D". As I couldn't start the Da Vinci Resolve program after I uninstalled it and all the attached software (including the DaVinci Control Panels). Now I've tried to install it on my Hard Drive "C" but everytime I do an information pops up that it "failed to install DaVinci Control Panels". Does anybody know how to fix this?
Cheers,
Nick
