Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, including supported operating systems and system requirements, see Citrix Product Documentation.

Known Issues in this Release

1. In rare cases, reinstalling this MSP file can cause the Citrix Display Driver (Citrix Systems – WDDM) to get marked for deletion. In turn, this causes the reinstall to fail, leaving the VDA’s display resolution unusable. As a workaround, restart the VDA and then reinstall the MSP. After restarting the VDA, the driver is removed. Then, when you reinstall the MSP, the drivers are successfully reinstalled.

New Fixes in This Release

1. Flash redirection fails for videos embedded on m.mlb.com and msn.com. A black rectangle appears in place of the video.

   To enable this fix, set the following registry keys:

   For mlb.com:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer\ASJSCallbacks
   Name: m.mlb.com
   Type: REG_MULTI_SZ
   Data: <place each value on a separate line, null separated>
   setPlaylist
   startPlaylist

   For msn.com:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer\ASJSCallbacks
   Name: msn.com
   Type: REG_MULTI_SZ
   Data:<place each value on a separate line, null separated>
   MsnVideoCallback
   MsnVideoPropertyCallback
   GetWidgetID

   This fix works only for Internet Explorer 9 and later. To allow this to work, set Internet Explorer to run in emulation mode and set Internet Explorer versions 9 and 10 to document mode. For more information, see article CTX136588 on the Citrix Support site.

Fixes from Replaced Hotfixes

1. Internet Explorer might close unexpectedly when attempting to play a video in web sites where:

   • The option "Disable Flash acceleration" is enabled or if the site is blacklisted.
   • The user is using a Receiver version that does not support Flash redirection such as Receivers for Mac OS X, iPad, iPhone, and Android.
