OpenSSL shows usage for openssl pkcs12 -export command on Windows?

Question

Am trying to generate a pcks12 file on Windows. I don't see what is wrong with my command run as administrator on Windows 7 64-bits. All input files exist. Alternately I get a usage or error "unable to load private key 5712:error:0906D06C:PEM routines".

Any help greatly appreciated! Bert

OK, got it! I mixed up the keys and -keysig is no longer required. Correct command was:

openssl pkcs12 -export -in c:\opensslkeys\server.crt -inkey c:\opensslkeys\rsakprivnopassword.key -out c:\opensslkeys\mypublicencryptionkey.p12
