I tried using 1.7.2 but nothing happens... ever. The program opens and I can add files. I can tell it to extract and choose where ... then nothing. No error no message no progress bar... nothing. What am I doing wrong? I tried 5 files that were all working with archiver, 7-zip, Stuffit(eww), ez-7z(just for 7z), and unarchiver. They all said the files were ok and extracted them but none of them are a good all-in-one like this is. I am willing to buy it if it is a good program but in my setup it is not even a working program.
