Inspirion 2 ins 1 7430 & active pen

Hi guys, I bought a Inspirion 2 in 1 7430 and be quite happy with it. Now, I bought an p5122w active pen. Now, I want to configure via dell periphery manager, but the software (latest version) don't offer the option to process as described in manual. Standard windows functions working, without the dell software but buttons on the pen are without function. Anyone has any tips for me? Thanks in advance
