7za-win32.exe is wrong version for 64-bit Windows

[georgedorn]

If you get a message like this on windows:

 *** OS: Windows 10 (win32)
 *** Mode: 2
 *** Working dir: c:\users\myuser\appdata\local\temp\Tingle-q_ewlx
 *** Decompressing framework...

Traceback (most recent call last):

  File "c:\Python27\lib\subprocess.py", line 212, in check_output
    process = Popen(stdout=PIPE, *popenargs, **kwargs)

    errread, errwrite)
  File "c:\Python27\lib\subprocess.py", line 640, in _execute_child
    startupinfo)
WindowsError: [Error 5] Access is denied

This is because the included 7za-win32.exe only runs on 32-bit windows. Despite the message at the top (Windows 10 (win32)) I'm running on x64.

A workaround for anybody else running into this problem:

1. Download and install 7Zip. The portable version is fine.
2. Look in the 7Zip install dir for 7z.exe
3. Copy 7z.exe to tingle\tools
4. Rename it to 7za-win32.exe so that the python script will find it.

Any 64-bit version of Windows that I know is able to run 32-bit executables. I also use it from a 64-bit version of Windows.

There must be a different problem, more related to permissions. I will look at it.

[georgedorn]

That is the case here, yeah. It is set to 'Read' for Everyone, but not 'Read & execute'. So not a 64/32-bit issue, though I have seen the same error when trying to run certain especially naive 32-bit executables in the past.

So the alternate workaround is to set the executable permission on 7za-win32.exe, either via Properties or chmod if you have a bash shell (like Cygwin).

@georgedorn I have fixed the permission. Now it also use the 64-bit 7za if Tingle is executed under 64-bit Python. So everything should work perfectly now.

Please test it and report back.
