Help me install my HP Pavilion webcam driver

Hi!

I am trying to install my HP Pavilion dv7-1245dx webcam driver. Whenever I click on Run, it would give me the black screen then nothing happens after. I saw a yellow triangle with an exclamation in HP Webcam and I tried to uninstall but after doing this, I couldn't find the HP Webcam anymore. I tried to install the webcam driver again but it is still doing the same.

Help me pls> I'm running Windows Vista Home Edition.

Thanks so much!
