ImportError: No module named yoton, after Windows 7/Office 2010 hotfix

[GoogleCodeExporter]

What steps will reproduce the problem?
1.upgraded windows 7 recently(but not sure which hotfix)

What is the expected output? What do you see instead?
See attachment

What version of the product are you using? On what operating system?
IEP 3.0, windows 7 + Office 2010

Please provide any additional information below.

1. after googling, it may VC runtime base related, but so far I got no 
solution, reinstall IEP/Python will NOT solve issue.

2. Can not install yoton package via MSI or easy_install - VC runtime error.

3. The problem gone by system restore to status before install hotfixes, once 
upgrade hotfixes, it comes again.

Very strange. Yoton is a package that comes with IEP. I can not think of a 
reason why it cannot be imported.

You say you think it might be related to the VC runtime. Reinstalling Python 
should fix that. Otherwise you can try and install the redistributable runtime:

Does your normal Python interpreter work ok?

reinstall VC runtime won't solve the issue. 
and normal python works fine, but yoton also not working 

C:\>python
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win

Type "help", "copyright", "credits" or "license" for more information.
>>> import yoton

The fact that you cannot import yoton from normal Python is ok; yoton is a 
packaged embedded in IEP. However, I do not understand why the IEP interpreter 
cannot find it ...

Let's do some remote debugging (if you feel like it) ...

Can you open the start.py (the file name is in the error message of your 
screenshot), and between "import sys" and "import yoton", add the following 
line:
print('PATH', sys.path)

Next, restart the IEP interpreter (no need to restart IEP itself), and see what 
it says?

This is not a IEP issue but a system optimize issue:

http://stackoverflow.com/questions/4895966/changing-default-startup-directory-fo
r-command-prompt-in-windows-7

after i set above post suggeted about cmd, the IEP can not find the right in 
subprocess path.

C:\>reg query "HKCU\Software\Microsoft\Command Processor" /v AutoRun

HKEY_CURRENT_USER\Software\Microsoft\Command Processor
    AutoRun    REG_EXPAND_SZ
^_____________this is OK

C:\>reg query "HKCU\Software\Microsoft\Command Processor" /v AutoRun

HKEY_CURRENT_USER\Software\Microsoft\Command Processor
    AutoRun    REG_EXPAND_SZ    CD /D %CMDAUTORUNPATH%
^____________this making trouble

Almar, can it be patched in IEP start.py? thanks.

Ah, so if I understand this correctly then:
IEP adds an empty entry to PYTHONPATH and sets the current working directory 
for the kernel process such that yoton can be imported. But apparently, the  
current-directory is somehow overridden in your case.

Can you please test the following:
  * in iep/source/iepcore/kernelbroker.py
  * in function getEnvFromKernelInfo()
  * Change "pythonPath = os.pathsep + pythonPath" 
    to     "pythonPath = iep.iepDir + os.pathsep + pythonPath"
  * Restart IEP
