On the basic question of why openssl is not found  Short answer Some installation packages for openssl have a default openssl cnf pre-included   Other packages do not  In the latter case you will include one from the link shown below  You can enter additional user-specifics --DN name etc-- as needed   From https   www openssl org docs manmaster man5 config html I quote directly    OPENSSL LIBRARY CONFIGURATION  Applications can automatically configure certain aspects of OpenSSL using the master OpenSSL configuration file  or optionally an alternative configuration file  The openssl utility includes this functionality  any sub command uses the master OpenSSL configuration file unless an option is used in the sub command to use an alternative configuration file   To enable library configuration the default section needs to contain an appropriate line which points to the main configuration section  The default name is openssl conf which is used by the openssl utility  Other applications may use an alternative name such as myapplication conf  All library configuration lines appear in the default section at the start of the configuration file   The configuration section should consist of a set of name value pairs which contain specific module configuration information  The name represents the name of the configuration module  The meaning of the value is module specific  it may  for example  represent a further configuration section containing configuration module specific information  E g     So it appears one must self configure openssl cnf according to your Distinguished Name  DN   along with other entries specific to your use   Here is the template file from which you can generate openssl cnf with your specific entries   One Application actually has a demo installation that includes a demo  cnf file   Additionally  if you need to programmatically access  cnf files  you can include appropriate headers --openssl conf h-- and parse your  cnf files using   CONF modules load file const char  filename  const char  appname                              unsigned long flags     Here are docs for  CONF modules load file

You should specify the absolute path to the config  something like this   openssl req -x509 -config  C  OpenSSL-Win64 bin openssl cnf
