Having just purchased an Active Pen PN556W, I am trying to install the Active Pen Control Panel on my Latitude 11 5175. Win 10 64 bit. The Active Pen Control Panel allows you to configure what the pen buttons do. I downloaded the latest driver/app from the dedicated Dell Lat 5175 support page: APP_IO_Driver_W8_W10_A00-SETUP-XYCTY_ZPE.exe. But when I try to install it stops after the unpacking / unzipping of files with the message: "A supported tablet not found on this system". The app/driver support details confirm that it is compatible with Win 10 64 bit and Lat 11 5175. I tried downloading some Wacom software to test and if I try to install the Wacom software it gives exactly the same message ”a supported tablet not found on the system” as you would expect as there is no Wacom tablet attached. It seems to me as if the Dell/Wacom software is looking for a “tablet” and not finding one i.e. a separate "tablet" that would be (USB?) connected to the system, rather than the standalone computer Dell 5175 "tablet" pc. So some confusion in terms between a computer “tablet” and the traditional separate plug in Wacom style drawing “tablet”. Could there be a setting somewhere that needs to tell the software that the "tablet" is actually part of the "system". Could I ask other 5175 owners if they have successfully installed the active pen control panel, or even download and try it on their tablet. (Download is about halfway down the page of 5175 drivers: http://downloads.dell.com/published/pages/latitude-5175-laptop.html ). Dell seem to be struggling to find a solution so any help would be much appreciated.
