Actually i have go through below discussion mention 7zip v9.20 can unpack the pk-aes256 file however while i try with same version was not work at all with above error 'Unsupported Method'
So my question: Is it 7zip v9.20 integrate the securezip algorithm so 7-Zip can decrypted such kind of files or any workaround solution i can used to decrypted the pk-aes256 files using the 7zip v9.20?
