About this release
XenApp and XenDesktop 7.15 LTSR Cumulative Update 3 (CU3) fixes more than 200 issues reported since the release of 7.15 LTSR CU2.
New in this cumulative update
Browser content redirection is a newly compatible component of XenApp and XenDesktop 7.15 LTSR, available as a separate download. For more information about browser content direction in this cumulative update, see Browser content redirection under XenApp and XenDesktop 7.15 LTSR CU3 compatible components.
How do I deploy CU3 from scratch?
You can set up a brand-new XenApp and XenDesktop environment based on CU3 - using the CU3 metainstaller. Before you do that, we recommend that you familiarize yourself with the product:
Peruse the XenApp and XenDesktop 7.15 LTSR (initial release) section and pay close attention to the Technical Overview, Install and Configure, and Securitysections before you start planning your deployment. Ensure your setup meets the system requirements for all components.
What do I update?
CU3 provides updates to baseline components of the 7.15 LTSR. Remember: Citrix recommends that you update all LTSR components of your deployment to CU3. For example: If Provisioning Services is part of your LTSR deployment, update the Provisioning Services components to CU3. If Provisioning Services is not part of your deployment, you do not need to install or update it.

Redirects the contents of a web browser to a client device, and creates a corresponding browser embedded within Citrix Workspace app. This feature offloads network usage, page processing, and graphics rendering to the endpoint. Doing so improves the user experience when browsing demanding webpages, especially webpages that incorporate HTML5 or WebRTC. Only the viewport (the user’s visible area of a webpage) is redirected to the endpoint. Browser content redirection doesn’t redirect the user interface (the address bar, toolbar, and so forth) of the browser on the VDA. For more information see Browser content redirection.
These requirements are specifically for the BCR.msi with XenApp and XenDesktop 7.15 LTSR CU3. Disregard any browser content redirection system requirements listed in any other versions of XenApp, XenDesktop, and Citrix Virtual Apps and Desktops.
- Version 7.15 LTSR CU3 on both the Delivery Controller and the VDA.
- Citrix Workspace app for Windows 1809 or later.
- BCR.msi - available from the Citrix download page.
- Chrome (with the browser content redirection extension installed from the Chrome WebStore) or Internet Explorer 11 (with the Browser Helper Object (BHO) Citrix HDXJsInjector enabled).
Install or upgrade the VDA with Version 7.15 LTSR CU3 by using the command line /FEATURE_DISABLE_HTML5 option.
This option removes the HTML5 video redirection feature, which must be done before running the BCR.msi. BCR.msi adds the feature back during installation, and also adds the browser content redirection services. When this step is complete, open the services.msc console and verify that the Citrix HDX HTML5 Video Redirection Service is not listed.
Start the browser content redirection installation with the BCR.msi. Depending on your system, the BCR.msi installs its files under:
Because the installation is fast, the dialog box might close quickly. If that occurs, rerun services.msc and verify that these services were added.
You can control policies using the HKEY_LOCAL_MACHINE registries on the VDA or the HDX Browser Content Redirection Citrix administration template for the Group Policy Management Console.
You can download the template from the citrix.com download page under Citrix Virtual Apps and Desktops (XenApp & XenDesktop) > XenApp 7.15 LTSR / XenDesktop 7.15 LTSR > Components. Citrix Studio does not contain these policies.

Install and upgrade analytics
When you use the full-product installer to deploy or upgrade XenApp or XenDesktop components, anonymous information about the installation process is gathered and stored on the machine where you are installing/upgrading the component. This data is used to help Citrix improve its customers’ installation experiences. For more information, see Install and upgrade analytics.
XenApp 6.5 migration
The XenApp 6.5 migration process helps you more efficiently and quickly transition from a XenApp 6.5 farm to a Site running XenApp 7.15 LTSR CU3. This is helpful in deployments that contain large numbers of applications and Citrix group policies, lowering the risk of inadvertently introducing errors when manually moving applications and Citrix group policies to the new XenApp Site.
After you install the XenApp 7.15 LTSR CU3 core components and create a Site, the migration process follows this sequence:
- Run the XenApp 7.15 CU3 installer on each XenApp 6.5 worker, which automatically upgrades it to a new Virtual Delivery Agent for Server OS for use in the new Site.
- Run PowerShell export cmdlets on a XenApp 6.5 controller, which exports application and Citrix policy settings to XML files.
- Edit the XML files, if desired, to refine what you want to import to the new Site. By tailoring the files, you can import policy and application settings into your XenApp 7.15 LTSR CU3 Site in stages: some now and others later.
- Run PowerShell import cmdlets on the new XenApp 7.15 CU3 Controller, which import settings from the XML files to the new XenApp Site.
Reconfigure the new Site as needed, and then test it.
For more information, see Migrate XenApp 6.x.
