Why Won't Program Install on Vista?

I am trying to install a program called Lanier VXP player. What this is is a device that plays files using a VPN connection to a hospital. I do medical transcription. I just got a new computer which has Vista on it. No one in the little company I work for has every tried this program with Vista. When I try to install it, it gets 96% done and then says it is installing "profiles/lanier healthcare/vxp player/drivers/winNT/joystick.sys" Then it comes up with an error saying "E:/drivers/winNT/joystick.dll" Any ideas what is going on? I would SO appreciate any help! Oh, and it also says "I/O device error (0x45d)"
