Issues with install on windows 'unable to get local issuer certificate'

[DannyShort]

I have been trying to troubleshoot this for a few days now but have got stuck. I and have added the certificate to my Trusted Root Certification Authorities as talked about in #360 but i am still getting the error unable to get local issuer certificate even though i can see the certificate is being accepted in the browser for the localhost page. Any ideas?

My final though is it because we are behind a proxy we had issues when first using nom & we had to configure our ca tour proxy certificate. Could it be this?
