I had the same problem running the izpack2exe.py script manually on a Windows 7 x64 machine. I made some adjustments to the python script, which now looks as follows:
import os
import sys
import subprocess
import shutil
import optparse
import shlex
def parse_options():
parser = optparse.OptionParser()
parser.add_option("--file", action="append", dest="file",
help="The installer JAR file / files")
parser.add_option("--output", action="store", dest="output",
default="setup.exe",
help="The executable file")
parser.add_option("--with-jdk", action="store", dest="with_jre", default="",
help="The bundled JRE to run the exe independently of the system resources. ") # choosen JDK that may came with the package
parser.add_option("--with-7z", action="store", dest="p7z",
default="7za",
help="Path to the 7-Zip executable")
parser.add_option("--with-upx", action="store", dest="upx",
default="upx",
help="Path to the UPX executable")
parser.add_option("--no-upx", action="store_true", dest="no_upx",
default=False,
help="Do not use UPX to further compress the output")
parser.add_option("--launch-file", action="store", dest="launch",
default="",
help="File to launch after extract")
parser.add_option("--launch-args", action="store", dest="launchargs",
default="",
help="Arguments for file to launch after extract")
parser.add_option("--name", action="store", dest="name",
default="IzPack",
help="Name of package for title bar and prompts")
parser.add_option("--prompt", action="store_true", dest="prompt",
default=False,
help="Prompt the user before extraction?")
(options, args) = parser.parse_args()
if (options.file is None):
parser.error("no installer file has been given")
return options
def create_exe(settings):
if len(settings.file) > 0:
filename = os.path.basename(settings.file[0])
else:
filename = ''
if len(settings.with_jre) > 0:
jdk = os.path.basename(settings.with_jre) #inside the jdk/jre that was given, there must be a bin/java.exe file
jdk = jdk + "\\bin\\javaw.exe"
print(jdk)

jdk = 'javaw' #java is added somehow to the PATH

if (os.access('installer.7z', os.F_OK)):
os.remove('installer.7z')
files = '" "'.join(settings.file)
p7zcmd = '7za.exe a -mmt -t7z -mx=9 installer.7z "%s"' % files

zip_proc.communicate()

config.write(';!#Install#!UTF-8!\n')

files = [sfx, 'config.txt', 'installer.7z']
output = open(settings.output, 'wb')
for f in files:
in_file = open(f, 'rb')
shutil.copyfileobj(in_file, output, 2048)
in_file.close()
output.close()
if (not settings.no_upx):
if settings.upx == 'upx':
upx = os.path.join(os.path.dirname(sys.argv[0]), 'upx')
else:
upx = settings.upx
upx = 'upx.exe --ultra-brute "%s"' % settings.output
upx_proc = subprocess.Popen(shlex.split(upx))
upx_proc.communicate()
os.remove('config.txt')
os.remove('installer.7z')
def main():
create_exe(parse_options())
if __name__ == "__main__":
main()
I statically put the 7za.exe in the p7zcmd variable which doesn't result in problems as it is on my path. I blocked the script execution until the subprocesses where done (7zip and upx respectively) which resolved my problems.
Hope I could help you.
