Q - Is Voyant compatible with Citrix and do you have any other clients using your software within a Citrix environment?
A - Yes, and there are numerous firms that use Voyant on Citrix.
Citrix administrators only need to ensure that their Citrix environment meets the basic requirements our software needs to run – e.g. Java must be installed and allowed communicate through their network out to our servers without blocking the download of files or scrubbing header information.
Other than the usual issues that might occur on any server or network (e.g. firewalls or permissions blocking our software from being downloaded, installed, or communicating with our servers) there is usually nothing special about running Voyant on Citrix. The server just needs to meet our basic operational requirements, as outlined here. Read more >>
Also, below are links to an installation guide and a guide to our software's operational requirements, should you or your IT department need them.
Java and Voyant would need to be installed and available to each instance (virtual client) that log into on Citrix when accessing Voyant.

The .jar and .pack.gz files contain binary data.
Some network firewalls alter or strip information from the headers of messages received through their networks. You will need to ensure that the headers in responses from our servers, which contain important version information, are not altered or stripped by any network proxy servers. The Java Web Start component of the JRE is looking for a specific header (x-java-jnlp-version-id) in the response from our web servers when it requests the application resources. On very rare occasions we have found that some firms operate through firewalls and/or proxy servers which remove these headers from the response.
If you would like to test this outside of the Java environment, the URL format for a versioned resource is as follows.
Below is the expected response as picked up by a network request monitoring tool (We used Fiddler with Firefox).

Authorised computer limits on Citrix
The main issue that crops up when running Voyant on Citrix is our check for authorised computers – usually we allow 2 computers to be authorised per licensee. On Citrix a user may be assigned per session to one of a number of virtual clients, they may quickly run up against our authorised computer limit. What we normally do for Citrix users is ask the users to register, creating their user accounts on our website, and contact us once registered. We can then switch off the authorised computer check for those user accounts.
