At last (as usual some months late just to avoid problems) I tried to install last available issue and, after a very complete cleaning from 9.3.037 (about ten years with ZA is a proper experience...), the new software...tells me immediately (first window).."No valid installation configuration found"...
Never seen before and never happened with previous issues.
Windows XP Home XP3, 2GB RAM, Toshiba M70
Any suggestion, please ?
Thank You in advance for any help !
