Do you have MSCV/MSVS installed? You need a C compiler for
"python
setup.py install" to work.<br>

</span><span style="font-size: 12pt;">No, but I have Python
installed on

<p class="MsoNormal"><span style="font-size: 12pt; font-family:

Not overly special - it is certainly not the only python
extension written
mainly in C. The majority of extensions however are just
python
themselves, so don't require a C compiler.<br>

Personally, I just use Michael Foord's PyCrypto Windows builds:

<br>
Then I don't need a compiler.<br>
