Unable to install 40002668_P driver

I am unable to install the driver 40002668_P for AnywhereUSB/14 on Windows Server 2012 R2. It simply does not run. I can install driver 40002668_N with no problems. I see no errors or messages in the event log. It is like the OS is not even trying to run the installer.

The device of some USB to Serial cables isn’t installed by default on 64-bit operating systems. These cables use unsigned device drivers and must be installed manually.
i am also unable to install this driver.
