Default [Q] ASUS ZenUI for Acer?

Hello,

i from Germany and my english is not good, please understand me, when im typing somethings wrong.

i have a Asus Padfone 2 Mobile Phone, now with Android 4.4.2.
and i have a Acer Iconia Tab A1-810 tablet with the same Android Version.

so, my questions is, i like the ZenUI from the Asus Device and i would like it too my Acer Iconia.

But, when i copy the file "ASUS Launcher" from the System of my Padfone to the Acer, and i will install it, then i have the anser:

App is not installed

then i can click only Finish and thats all.

Can anyone of this big community help me ?

Thanks from Germany
