What steps will reproduce the problem?
1. Fresh installs of 3.3.2.1 or 3.3.2.0.
2. IPython, SPyder, WinPython shortcuts crash silently.
3. Double-click on python.exe in python-3.3.2.amd64 folder.

What is the expected output? What do you see instead?
Python.exe won't start on my work desktop; raises a 0xc000007b error. But it works on my personal laptop.

What version of the product are you using? On what operating system?
64-bit 3.3.2.1 or 3.3.2.0 crash on my Windows 7 Pro work desktop.
64-bit 3.3.2.0 works on my Windows 7 Home laptop (haven't tried 3.3.2.1).
64-bit 2.7.5.1 works on both machines.
32-bit versions work on both machines.

Please provide any additional information below.
Used Dependency Walker to find that MSVCR100.dll in the python-3.3.2.amd64 folder is a 32-bit version. Downloaded the MS redistributable package to get a 64-bit version, copied it into the above folder, and now everything appears to work (although it sometimes takes a second attempt). Perhaps my laptop was able to use the correct DLL from a different location.

    I confirm that the embedded DLLs in WinPython 64bit 3.3.2.1 are in fact 32-bit versions due to an anomaly on one of my build machines. I've already implemented a way to avoid such architecture mismatch in the future but I haven't found a way to fix this machine configuration. In the meantime, I'll build WinPython with another machine (don't have the time to dig further unfortunately).

    WinPython 32bit 3.3, 32bit 2.7 and 64bit 2.7 are indeed not affected by this bug.

    I would very much appreciate it if you could roll out a new release with this fix. My university is planning to use WinPython for its upcoming introduction to programming and we have to start distributing the software to the university computers soon.

    When do you think the next release of winpython 3.3 Win64 will be released?

    I'll try and look into it next week and I should be able to make a new release during next week.

    This should be fixed with v3.3.2.2, hopefully.
