I am trying to install Python 3.5.0b2 on Win 8.1 but cannot get it loaded

http://pastebin.com/hKU2bvds

the error. hoping some one can help.

1) your paste appears to be invalid. You can just paste in a message here, or attach a screenshot (though text is preferable :))
2) 3.5.0b2 is out of date, try with beta 3 (or beta 4, due out this weekend)

http://pastebin.com/D5eVxF1b

Sorry, try this where to get the latest version pls..

Are you being promoted for administrative privileges? Unfortunately there's no way around requiring them to install the C Runtime update, so if you are blocked from applying Windows Updates to your machine unfortunately there's no good way around this.

Alternatively, do you have VS 2015 final release installed? This may be an error due to attempting to downgrade (3.5.0b3 was built with a prerelease version of VS), though it shouldn't be failing because of that.

Steve, I have Admin privilege

So I've done some quick research but don't have a lot of time. You're getting error code 0x80240017 from wusa.exe, which is trying to install a Windows Update.

This thread looks like it may have some solutions on it: http://answers.microsoft.com/en-us/windows/forum/windows_8-winapps/installing-and-updating-built-in-apps-not-working/57ae6edc-0df2-46da-9a96-106cc4098c78 looked like

Can is there and equivalent for iPad? Mean, can Python code be written on an iPad; because still a headache to get it loaded on Windows 8.1

Are you aware that 3.5.0b4 has been released?  See https://www.python.org/downloads/release/python-350b4/

I was able to load Python 3.2.3. I set up Eclipse with PyDev now I try it with print("hello world"); and got this error. 

Mark unable to load 3.50b4 same error in log.

Fatal Python error: Py_Initialize: can't initialize sys standard streams
LookupError: unknown encoding: MS874

If you download and install the VC++ Redistributable from http://www.microsoft.com/en-us/download/details.aspx?id=48145 then we won't try and run the code that is failing in our installer.

If the previous installer fails then you have a configuration error on your machine and will need to resolve that before installing Python.

Steve had this installed before, however I uninstall it and ran it again, from the link you provided, below is the result. It now fail to be installed. Truly struggling as to why.

I don't know either. Below I've pasted the part of your log that shows the error and error code - you should contact your support department or (better) search the internet for that error code:

Thanks Steve will go to the Acer on Friday see what they say

SOLVED:

The PC errors were solved by doing the following. I found this after doing some extensive search.

hxxps://social.msdn.microsoft.com/Forums/en-US/10b9c8b4-7e49-4724-bca4-6ee5f4ec8a10/visual-studio-2015-professional-fails-to-install-on-windows-7?forum=vssetup

 I first ran the batch file at the end of the post.

 I then install KB2919442-x64.msu.

 Next I install KB2919335-x64.msu.

 Next I force windows 8.1 update

 I then download the vs2015.ISO extracted the Win 8.1 patch KB2999226-x64.msu and installed that. 

Install .netframeworks and then VS2015 finally Python 3.5.0b4 then reboot.

Now I have issues with "Hello World" in Eclipse Mars giving an error would appreciate any help. Thanks

Since this has been conclusively shown to not be a Python bug, closing the issue.

This isn't a support forum, you'll have to look elsewhere for help with Eclipse.
