My setup-x86_64 (version 2.881 from 2017-07-05) does not upgrade to this 
new version.
My liblz4_1 is at version 131-1 and setup propose to "Keep" it. It does 
not appear on "Pending" view.

Maybe some comparison inside setup.exe think that "1.7.5-1" <= "131-1" ?

Other updates were proposed and executed.
Version 1.7.5-1 is proposed by clicking 3 times on "Keep" (after 
"Reinstall" and "Uninstall").

Below the setup.ini part, showing 1.7.5-1 as "Current" and 131-1 as "Prev"
