New issue 260: Fatal Python error when running 32bit Python via tox on Windows
https://bitbucket.org/hpk42/tox/issue/260/fatal-python-error-when-running-32bit
Florian Bruhin:
With this tox.ini:
```ini
[testenv]
commands = {envpython} -c 'print("Hello World")'
basepython = C:\Python34_x32\python.exe
```
and a minimal setup.py:
```python
from setuptools import setup
setup()
```
I get this when running it on Windows:
```

Fatal Python error: Failed to initialize Windows random API (CryptoGen)
Running virtualenv with interpreter C:\Python34_x32\python.exe
ERROR: InvocationError: C:\Python34\python.exe -m virtualenv --python
C:\Python34_x32\python.exe py34 (see
C:\Users\florian\proj\qutebrowser\test\.tox\py34\log\py34-0.log)
```
Searching for the error [it seems](http://bugs.python.org/issue20614) this
happens when `SYSTEMROOT` is not set.
Even though `SYSTEMROOT` is printed in the environment above, I tried to add
`passenv = *` and `setenv = SYSTEMROOT=C:\Windows` without any success.
When I run that Python install by hand, it works fine. When I use a 64bit
install instead of the 32bit one on the same machine, it's fine as well.
I also tried downgrading to 1.9.2 and it happens there as well, so it doesn't
seem to be a recent `passenv` change.
