Dear Sirs,
The finger print reader of my HP probook 6440b was working fine untill it suddenly stopped doing so.
While trying to find solution I noticed that the biometric was absent from the device manager too.
Following suggestion found in internet, I reinstalled the driver “Validity”.
The I tried to (re)install DigitaPersona. While installing this software an error message appeared regarding DPCrProv.dll HRESULT -2147024769.
The finger print reader still doesn’t work. Also, each time I open or close my laptop a warning meassage appear saying that the source DPFP authenticate isn’t found in the librairy DPFPApi.dll. The logo for finger print desapeared.
There are many softwares already installed in my computer such as HP Protect tools security manager. May be was a mistake to install DigitaPersona.
Could you please help me to fix this problem. Thank you
Sincerely,
