Error in pkcs12 while executing command

Error in pkcs12 while executing command

I am trying to generate the .p12 file using the command as suggested in the document here

https://www.manageengine.com/products/passwordmanagerpro/help/faq.html#3.3

Section 2.4

However, I am getting this error: 

pkcs12: Use -help for summary.
error in pkcs12

The command I am using is 
pkcs12 -export -in C:\Certificates\mdpmpro\PMPRO.cer -inkey C:\Certificates\mdpmpro\pmpro.key -out C:\Certificates\mdpmpro\pmpro.p12 -name Password Manager Pro -CAfile C:\Certificates\mdpmpro\certnew.cer -caname Password Manager pro12 -chain

Can anyone help me how to resolve this one?
