Version of msvcrXX.dll that my Python interpereter compiles with

I have compiled my Python 3.3 application to a .exe with cx_Freeze and it's only run on my local machine.

On another computer, first it had an issue with a missing DLL, msvcr100.dll. After I installed Microsoft Visual C++ 2010 Redistributable Package on that computer, it doesn't show any errors, but still doesn't work because nothing opened.

I think that I installed wrong version of Microsoft Visual C++ Redistributable. How can I find out the version of msvcrXX.dll that my Python interpreter compiled with?

Python 3.3 is compiled with Visual Studio 2010. That uses Msvcr100.dll.

You can view the compiler via sys.version or platform.python_compiler():

Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> import platform
>>> sys.version
'3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) [MSC v.1600 64 bit (AMD64)]'
>>> platform.python_compiler()
'MSC v.1600 64 bit (AMD64)'
>>> ^Z

This is Visual Studio 2010's compiler version:

C:\>cl
Microsoft (R) C/C++ Optimizing Compiler Version 16.00.40219.01 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

usage: cl [ option... ] filename... [ /link linkoption... ]

More directly, you can example the DLL imports of the Python DLL directly:

C:\>dumpbin /imports c:\windows\system32\python33.dll | findstr /i dll
Dump of file c:\windows\system32\python33.dll
File Type: DLL
    KERNEL32.dll
    USER32.dll
    ADVAPI32.dll
    SHELL32.dll
    MSVCR100.dll
