Viewsonic P22f CRT Monitor Driver for Vista 64-bit

Dear,
I have Viewsonic P225f CRT monitor. My desktop computer has Microsoft Windows Vista Ultimate 64-Bit operating system. I want driver suitable for 64-bit. I had tried to install unsigned/signed driver from Viewsonic web site but installation encountered problems. I have a gaming system see specifications below, so I want to install Viewsonic monitor driver instead generic driver. I can send you error details as attachment if you mail me link. Kindly solve this driver problem.

Thanks
