unpackcmd = xz.exe -d -c <stdin> <stdout>

It achieves 99~100% but at the end shows this error:

ERROR: general (de)compression error in xz

Any clues?

Usage: xz [OPTION]... [FILE]...
Compress or decompress FILEs in the .xz format.

Mandatory arguments to long options are mandatory for short options too.

 Operation mode:

  -z, --compress      force compression
  -d, --decompress    force decompression
  -t, --test          test compressed file integrity
  -l, --list          list information about .xz files

 Operation modifiers:

  -k, --keep          keep (don't delete) input files
  -f, --force         force overwrite of output file and (de)compress links
  -c, --stdout        write to standard output and don't delete input files
      --single-stream decompress only the first stream, and silently
                      ignore possible remaining input data
      --no-sparse     do not create sparse files when decompressing
  -S, --suffix=.SUF   use the suffix `.SUF' on compressed files
      --files[=FILE]  read filenames to process from FILE; if FILE is
                      omitted, filenames are read from the standard input;
                      filenames must be terminated with the newline character

      --files0[=FILE] like --files but use the null character as terminator

 Basic file format and compression options:

  -F, --format=FMT    file format to encode or decode; possible values are
                      `auto' (default), `xz', `lzma', and `raw'
  -C, --check=CHECK   integrity check type: `none' (use with caution),
                      `crc32', `crc64' (default), or `sha256'
      --ignore-check  don't verify the integrity check when decompressing
  -0 ... -9           compression preset; default is 6; take compressor *and*
                      decompressor memory usage into account before using 7-9!
  -e, --extreme       try to improve compression ratio by using more CPU time;
                      does not affect decompressor memory requirements
  -T, --threads=NUM   use at most NUM threads; the default is 1; set to 0
                      to use as many threads as there are processor cores
      --block-size=SIZE
                      start a new .xz block after every SIZE bytes of input;
                      use this to set the block size for threaded compression
      --block-list=SIZES
                      start a new .xz block after the given comma-separated
                      intervals of uncompressed data
      --flush-timeout=TIMEOUT
                      when compressing, if more than TIMEOUT milliseconds has
                      passed since the previous flush and reading more input
                      would block, all pending data is flushed out
      --memlimit-compress=LIMIT
      --memlimit-decompress=LIMIT
  -M, --memlimit=LIMIT
                      set memory usage limit for compression, decompression,
                      or both; LIMIT is in bytes, % of RAM, or 0 for defaults
      --no-adjust     if compression settings exceed the memory usage limit,
                      give an error instead of adjusting the settings downwards

 Custom filter chain for compression (alternative for using presets):

  --lzma1[=OPTS]      LZMA1 or LZMA2; OPTS is a comma-separated list of zero or
  --lzma2[=OPTS]      more of the following options (valid values; default):
                        preset=PRE reset options to a preset (0-9[e])
                        dict=NUM   dictionary size (4KiB - 1536MiB; 8MiB)
                        lc=NUM     number of literal context bits (0-4; 3)
                        lp=NUM     number of literal position bits (0-4; 0)
                        pb=NUM     number of position bits (0-4; 2)
                        mode=MODE  compression mode (fast, normal; normal)
                        nice=NUM   nice length of a match (2-273; 64)
                        mf=NAME    match finder (hc3, hc4, bt2, bt3, bt4; bt4)
                        depth=NUM  maximum search depth; 0=automatic (default)

  --x86[=OPTS]        x86 BCJ filter (32-bit and 64-bit)
  --powerpc[=OPTS]    PowerPC BCJ filter (big endian only)
  --ia64[=OPTS]       IA-64 (Itanium) BCJ filter
  --arm[=OPTS]        ARM BCJ filter (little endian only)
  --armthumb[=OPTS]   ARM-Thumb BCJ filter (little endian only)
  --sparc[=OPTS]      SPARC BCJ filter
                      Valid OPTS for all BCJ filters:
                        start=NUM  start offset for conversions (default=0)

  --delta[=OPTS]      Delta filter; valid OPTS (valid values; default):
                        dist=NUM   distance between bytes being subtracted
                                   from each other (1-256; 1)

 Other options:

  -q, --quiet         suppress warnings; specify twice to suppress errors too
  -v, --verbose       be verbose; specify twice for even more verbose
  -Q, --no-warn       make warnings not affect the exit status
      --robot         use machine-parsable messages (useful for scripts)

      --info-memory   display the total amount of RAM and the currently active
                      memory usage limits, and exit
  -h, --help          display the short help (lists only the basic options)
  -H, --long-help     display this long help and exit
  -V, --version       display the version number and exit

With no FILE, or when FILE is -, read standard input.
