#21 Cant install for Python 3.4.3 (x64)

[Demian]

Can't install pygi-aio-3.14.0_rev19-setup.exe for my Python 3.4.3 (64 bit). Windows 8.1 x64.
"Setup cant find supported Python..." Than I press "Yes" and specify its location. "C:\Program Files\Python34\", press Ok button and nothing changes.

This is how it looks in IDLE (I saw that question in closed tickets).

::python

import distutils.sysconfig
print (distutils.sysconfig.get_python_version())
3.4
print (distutils.sysconfig.get_python_lib())
C:\Program Files\Python34\Lib\site-packages
import sys
print (sys.maxsize)

Could it be that DOS 8+3 filename generation disabled in your system?

[Demian]

I check that with command "fsutil behavior query Disable8dot3 c:" and it says to me that it in "1" state. (Disabled) Should I Enable that for this instalation?

[tumagonx]

I really sorry due to current circumstance of using batch file as part of setup. It need 8+3 path if encounter very long path/path contain unicode/space character.

[Demian]

It means, that I need use fsutil behavior set 0 for Enabling the DOS filename generation?
I really don't know, how it works in that way. I think, it's not a problem, if I set that in "Enabled" state. Yes?
Maybe it is, because i have "Program Files" through path? :)

[tumagonx]

Yes, the default is enabled. It probably set to disabled by 3rd party optimization utility

[Demian]

""" I find a reply button! :D """

Should I leave it or change state back into "Disabled" after installation? (I'll try now, while you leave reply. :) )

[tumagonx]

yes please leave it enabled, in modern harddisk disabling 8.3 filename didn't significantly improve performance anyway

[Demian]

Having same problem after typing "fsutil behavior set disable8dot3 2" and "fsutil 8dot3name set C: 0"

EDIT: Maybe I'm missing something important in that installation?

[Demian]

I have 1st, click Yes, than I have 2nd, click Yes, than 3rd here is my Python 3.4.3. and click Ok, and nothing changes.

[tumagonx]

try the following test
open cmd box at program files\pythonxx
type
for %f in ("%cd%") do echo %~sf

if doesn't return 8+3 name eg. progra~1 or similar then it still not generated/disabled, please try look for this issue in superuser.com

It's working now! Thank you very much! The answer is here => http://superuser.com/questions/681330/how-to-force-short-name-8dot3-generation

There is an option to keep the scripts working for now:

You could create a directory-junction from PROGRA~1 to C:\Program Files. That way the scripts keep working and you have time to change them.

mklink /J "C:\PROGRA~1" "C:\Program Files"
