I just downloaded the last openvpn-install-2.3.17-I001-i686.exe (for Windows XP)
I am following this guide:
https://openvpn.net/index.php/open-source/documentation/howto.html#pki
But when I start build-dh.bat I obtain this warning:
WARNING: can't open config file: /etc/ssl/openssl.cnf
I found the solution is to set OPENSSL_CONF with this command:
set OPENSSL_CONF=%HOME%\openssl-1.0.0.cnf
Can You please update the build-dh.bat file ?
