Not being an expert, I can only tell you how *I* got it to work.  I
exported my cert in IIS as a pfx file, and then import it via openssl. 

I did something like so:

$ openssl pkcs12 -in exported_cert.pfx -out cert.perm -nodes

It prompted me for my password (set at export time), and then I was able
to configure the SSL protocol preferences in Wireshark to read the file.  

Hope that is of some use.
