Change:

struct.unpack('!8siiii64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))

To:

struct.unpack('!8sIIII64s', self.fPtr.read(self.PYINST21_COOKIE_SIZE))

Will solve this error:

[+] Pyinstaller version: 2.1+ [+] Python version: 3.7 -2089571957 [+] Length of package: -2089571957 bytes [+] Found 4480 files in CArchive [+] Beginning extraction...please standby Traceback (most recent call last): File "pyinstxtractor.py", line 456, in main() File "pyinstxtractor.py", line 445, in main arch.extractFiles() File "pyinstxtractor.py", line 279, in extractFiles data = zlib.decompress(data) zlib.error: Error -5 while decompressing data: incomplete or truncated stream

And these place, change to unsign int

nameLen = struct.calcsize('!IIIIBc')

(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) = \ struct.unpack( \ '!IIIBc{0}s'.format(entrySize - nameLen), \ self.fPtr.read(entrySize - 4))

Might be built with a modified pyinstaller.

nameLen = struct.calcsize('!IIIIBc')

(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) = struct.unpack( '!IIIBc{0}s'.format(entrySize - nameLen), self.fPtr.read(entrySize - 4))

iiii to IIII , signed integer to unsigned integer.

search and replace these code also:

nameLen = struct.calcsize('!IIIIBc')

(entryPos, cmprsdDataSize, uncmprsdDataSize, cmprsFlag, typeCmprsData, name) = struct.unpack( '!IIIBc{0}s'.format(entrySize - nameLen), self.fPtr.read(entrySize - 4))
