<div dir="ltr">Hi,<br>I have a problem installing PyCrypto.<br>I tried to install it on my Win7 machine using "setup.py install". I have Python 2.6.4 installed.<br>It created folders under lib\Crypto and copied files, but when it reached the build part I receive:<br>
<br>running build_ext<br>warning: GMP library not found; Not building Crypto.PublicKey._fastmath.<br>building 'Crypto.Random.OSRNG.winrandom' extension<br>error: Unable to find vcvarsall.bat<br><br>What should I do?<br>
What and where is this vcvarsall.bat?<br>Thanks<br> Jonathan<br></div>
