As BigRandalo suggested, this can be done easily yourself. Just download the new innounp and overwrite the older innounp.exe in the UniExtract bin\ directory. I don't plan on adding any automatic support for this, as new versions may behave differently and as a result break UniExtract if it's not properly tested. Hi nitro322 New version of innounp (0.20) works well with new version of inno setup but in uniextract no, it uses cmdtotal and files are bad. cause: peid internal scan not recognize new version of inno setup (show Borland Delphi 2.0 overlay) My solution: 1) I add external signature to peid and modify this line $scantypes = _ArrayCreate('deep','hard','ext') to $scantypes = _ArrayCreate('ext', 'deep','hard') 2) modify this line case stringinstr($filetype, "Inno Setup Installer", 0) to case stringinstr($filetype, "Inno Setup", 0) 3) modify this line if (stringinstr(filereadline($debugfile, 1), "Version detected:", 0) _ to if (stringinstr(filereadline($debugfile, 1), " Version detected:", 0) _ All now works. Old bug: if folder already exist uniextract shows error but it extracts anyway.
