The quickest solution is  set environment variable RANDFILE to path where the  random state  file can be written  of course check the file access permissions   eg  in your command prompt   set RANDFILE C  MyDir  rnd openssl genrsa -out my-prvkey pem 1024   More explanations  OpenSSL on Windows tries to save the  random state  file in the following order    Path taken from RANDFILE environment variable If HOME environment variable is set then     HOME   rnd C   rnd   I m pretty sure that in your case it ends up trying to save it in C   rnd  and it fails because lack of sufficient access rights   Unfortunately OpenSSL does not print the path that is actually tries to use in any error messages
