Just installed personalization tool (3.1.24)(1.17.3) but it won't read my Yubikey. Error message is "Unknown error occurred". The Yubikey green light is on and I am logged on as an administrator. The Yubikey authenticates successfully on the Yubikey web site.
In case this may help I had also installed (upgraded) to Lastpass (4.0.3) and my Yubikey stopped working. After much contact with Lastpass technical support I had to disable multifactor verification.
