Ok, I found this:
https://support.comodo.com/index.php...le/View/548/7/

it's tricky.. I don't know if it works yet, but it created my pvk, pem,
and .spc files. I downloaded openSSL win32 v1.10f. and followed the
instructions. I'm sure there is an easier way. I'll post here if the
code signing now works.
