Cannot connect to the citrix presentation server. SSL Error 61: You have not chosen to trust “Thawte Server CA”, the issuer of the server’s security certificate.
To resolve, I knew I needed the root CA cert.  I then stumbled upon the root CA download location for Thawte.

Once downloaded and installed the right cert, citrix began working again.  Another problem solved by google and hitting my head against my desk a few dozen times…

“The archives required to make an SSL connection are not available. Please contact your Citrix Administrator”

The bizzare thing is that he has citrix client installed and everything should work. Well, I did a little bit of searching on the web, and I found the following resolved the issue.

For Web Interface 4.x:

In the Access Suite Console, go to Web Interface > Manage Client Deployment and select the SSL/TLS check box on the Client for Java page.

I also had to enable the Java client as well. This was done in Select Launch Clients area of the install.
