Did you reinstall all your Adobe apps after updating the OS?
hi Larry, thank you. no, I just upgraded Windows 7 to Windows 10, and tested the cs5 software. everything ok except for indesign that asks for sn, but doesn't accept the right one. maybe important: my suite is in italian, but indesign, now, is in english.
perhaps I solved uninstalling indesign and reinstalling as trial version because of the sn wasn't accepted. at the second start up it seems to be ok. how can I check if it is actually ok or still trial version?
