Hi,

I recompiled my application as a console program and got following error 
message:

-----------------------------------------------------------------------
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>e:\AUTORUN.EXE
Traceback (most recent call last):
   File "D:\PROGS\Python23\lib\site-packages\py2exe\boot_common.py", 
line 69, in ?
     import linecache
zipimport.ZipImportError: can't decompress data; zlib not available
Traceback (most recent call last):
   File "AutoRun.py", line 54, in ?
zipimport.ZipImportError: can't decompress data; zlib not available
-----------------------------------------------------------------------

so I removed "compressed": 1, from setup.py and it WORKS!!!
This seems to be a bug in py2exe ????

Thanks a lot
Werner
