For those people also running Windows 7 64 bit on a HP HDX 18 laptop :
This is how you get the fingerprint sensor driver & program working again :
- Download the Validity Fingerprint Sensor Driver from:
ftp://ftp.hp.com/pub/softpaq/sp45001-45500/sp45050.exe - Download Digital Persona 4.0.1.3749 64 A from:
ftp://ftp.hp.com/pub/softpaq/sp43501-44000/sp43883.exe - Install the driver (sp45050)
- Install Digital Personal (sp43883)
Reboot and it should work fine. If you run HP update then Digital Persona will also work with Firefox. (Install latest version of Firefox)
They should probably go onto most of the HDX16 and HDX18 pages.
