Driver Installation Error Message

I am trying to install a driver and Windows won't allow it. The Windows error message says it may be harmful and there is no option in the error message box to override the message. I am the administrator on the system. Does anyone have a solution?
My OS is Windows Vista 64 bit.

Thanks

 

We need more information,
what driver are you trying to install,
what is the exact error message

 

The error message is in a Windows Security Warning box.

Message: "To help protect your computer, windows has blocked access to this file"

Driver: PL-2303 Vista Driver Installer.exe It is a driver for a golf GPS unit.

Thanks
