Sybase ASE 16.0 install problem on Windows 7

Hello,

Just downloaded Sybase ASE 16.0 Developer Edition to test on my Windows 7 ... (ase160_winx64.zip) from:
https://global.sap.com/campaign/ne/sybase/ase_developer_edition_download

Sybase ASE 15.7 is already installed, assuming that 15.x and 16.x versions can co-exist on same machine.

I get installation errors in the ASE_Suite.log

Note that I have to unzip the archive on my Linux because the ase160_winx64.zip file is not identified as a valid zip file... (???)

Can someone help?

Thanks!
