Sankey Diagram in QV12

[Steffen_Obst]

Hello,

can someone explain (step by step) how i can add (Install!) and use the sankey diagram extension in QlikView 12.

I've got only this link and dont know what to do.

I tried to install the extension by click on sankey.qar, but get "invalid archive" and "0 files were istalled in 0 directories"

thx

Steffen
