GM,
I just decided to update my Mac Pro (Mac OS High Sierra 10.13.6) from GanttProject 2.8.5 Pilsen to the 3.0 release, but running the exe for installing it, a lot of errors come out form the Unarchiver (see attached shot of the first message (of a lot of other similar messages - sorry, the country language is Italian). By hitting “Continue” at every message, at the end the result is to have only a folder in the download, which 3 subfolders named with ideograms.
How can I solve the problem and install version 3.0 successfully?
Thank you in advance.
Alberto.
