Hello, With the new version providing better options with GPO, we have decided to test and deploy into our XenApp 6.5 / Windows Server 2008 R2 environment. Unfortunately, it has failed at the first hundle. Post installation and running for the first time, no pages load. The Tab will show the loading animated icon, but will never load the page. I cannot even get to Options (about:preferences). Has anyone else experienced the similar issue and know of a resolution? Thank you, Adam.
