Made this to help out
Found out how to make it work, just enable compatibility mode and change the compatibility to windows 8 of the digitalpersona's DPAgent.exe and dphostw.exe, you can do this via task manager and right clicking the apps related to digitalpersona and choosing properties then choose compatibility tab. if you it still doesn't work, install the validity driver, but don't install it directly, just extract it and run the installer in compatibility also to windows 8. Restart your PC! cheers!
