Class not registered 0x80040154 (02147221164) When running CertReq

Hi Im trying to create a certificate with using a SAN.

When I run the following command I get receive this error

My certreq.ini is as follows

[NewRequest]
Subject="CN=nashcaspri.nashuact.uct.ac.za,OU=ICTS - Technical Support Services,O=University of Cape Town,L=Rondebosch,S=Western Cape,C=ZA"
Exportable=TRUE
KeyLength=2048
KeySpec=1
KeyUsage=0xf0
MachineKeySet=FALSE
 
[EnhancedKeyUsageExtension]
OID=1.3.6.1.5.5.7.3.1
OID=1.3.6.1.5.5.7.3.2
 
[RequestAttributes]
SAN="dns=ccpdashboard.uct.ac.za"

I am using Windows server 2012 with IIS 7.5 , Can anyone tell me if I have done something wrong or if something is missing from my server.

Thanks

Andy
