"application was unable to start correctly 0xc0000005" Python error on windows 7

I spend 3 hours banging my head against wall to find the exact solution.

Its not b but 5 at the end so it is not graphics driver issue.

Luckily, I have three Python versions installed on my system; one 32 bits and two 64 bits.

Here, culprit is corrupted Microsoft VC++ libraries(runtime)

Simple trick is:

To repair installation of Microsoft VC++ libraries through ADD REMOVE PROGRAMS.


Try to run python shell, it should work now.

Getting error while installing pip or setuptools

Python has weird as well as awesome tool known as pip.

Main precaution to take care is never ever leave half baked python packages installed as they are main reasons for dependency problems.

https://stackoverflow.com/questions/16144934/trouble-install-pip-windows

pip can be upgrde or downgrade using same command:

python -m pip install --upgrade boto3

It looks like a bug in pip where it's assuming its metadata is stored as UTF-8. Instead, your username appears to be encoded as "windows-1255".

You could try the following:

File "C:\Users\name\ AppData\Local\Programs\Python\Python35-32\lib\site-packages\pip\_vendor\pkg_resources\__init__.py", line 1616, in get_metadata
    return self._get(self._fn(self.egg_info, name)).decode("utf-8")

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf2 in position 22365: invalid continuation byte
You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

https://stackoverflow.com/questions/35510743/error-while-upgrading-pip-unicodedecodeerror-utf-8-codec-cant-decode-byte

1. Backup: C:\Users\name\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pip\_vendor\pkg_resources\__init__.py
2. Goto line: 1616
3. Change utf-8 to mbcs.
4. Re-run upgrade

Not detecting any Wireless/Wifi Network in CentOS 7

Here is my experience, for the following reasons:


  1. If you got connected to Wifi network when you have installed CentOS 7.
  2. After CentOS 7 entering into sleep mode OR accidental shutdown due to power
    drainage OR you have restarted & logged into CentOS 7

and if your wifi not working.

Don't install extra kernel module OR install any new packages OR do any tweak.

Just shutdown and boot again in CentOS 7. Your wifi will start working again.


Bottom Line:  This is what I realised after 6 hours of tweaks and tried everything out.
