Finally.. I did it.
For the people that can't install the PS3Eye in latest windows 7 x64:
1- Install the lastest drivers "PS3Eye Camera Setup v3.0.0.0901" (thanks to AlexP).
2- Plug your cam. Windows says it cant find the drivers.
3- Go to Device Manager and find your cam (for me USB camera-B3.04.06.1). Right click and select update software driver, select install software driver manually.
4- Then explore to go to C:\Program Files (x86)\AlexP .
5. Follow instructions.
It works for me, I hope this can help more people than me. My english is not good I hope that everybody can understand me.
Regards.
P.D: Don't forget to give thanks to AlexP.
PD2: I dont know if this can works in another windows version.
