Hello,

I have previously had problems with Fences and certificates, I have added that thread in these forums as a link in this post.

My workplace has pushed some new security settings and fences won't run.  When I go to fences.exe -> properties -> Digital Signatures, I can select the "Stardock Corporation" signature and press the "Details" button.  

Windows shows an error icon and says "The revocation process could not continue - the certificate(s) could not be checked."

When I go to the View Certificate button, I get an error "Windows cannot determine the validity of this certificate because it cannot locate a valid certificate revocation list from the certification authority that issued this certificate."

I can see at the bottom that it is Issued by: "COMODO Code Signing CA 2" and valid from 10/3/2011 to 10/3/2014.

So it appears that something has expired.  I have already tried downloading "AddTrustExternalCARoot" from COMODO's site and installing it but that hasn't worked.

Before I go on, is there any advice that stardock can offer?  Is there a newer exe?  (I'm running 2.13).  

Thanks!
