The installation creates the following entries for the App-V client in Programs :. Install all of the required prerequisite software on the target computers. See What to do before you start. If you install the client by using an. To use a script to install the App-V 5. The client Windows Installer. The following options are enabled: [1]; automatically load all packages [2]; or automatically load no packages [0].
The parameter prevents the end-user computer from rebooting after each update is installed and lets you schedule the reboot at your convenience. For example, you can install App-V 5. After the installation, you must reboot before you start using App-V. This is required for an unattended installation.
It also extracts the Windows Installer. No value is expected. Requires a string value. If any prerequisites are not met, the installation will fail. Ensure that the target computers do not have any pending restarts before you install the client using the App-V 5. The Windows Installer files do not flag a pending restart. Deploy one of the following Windows Installer files to the target computer.
The file that you specify must match the configuration of the target computer. Using the information in the following table, select the appropriate language pack. The xxxx in the table refers to the target locale of the language pack.
The language packs are common to both the standard App-V 5. If you install the App-V 5. To deploy additional language packs on a target computer, use the procedure To install the App-V 5. This operation completely loads the entire package into the package store. The App-V Client can be configured to change the default behavior of streaming. The following policies apply to streaming:. These settings affect the behavior of streaming App-V package assets to the client.
By default, App-V only downloads the assets required after downloading the initial publishing and primary feature blocks. There are three specific behaviors in streaming packages that it's particularly important to understand:. Background streaming is a default setting where the Autoload setting is set to download previously used packages.
App-V packages can be configured with a primary feature block during sequencing. This setting allows the sequencing engineer to monitor launch files for a specific application, or applications, and mark the blocks of data in the App-V package for streaming at first launch of any application in the package. After the initial stream of any publishing data and the primary feature block, requests for additional files perform stream faults. These blocks of data are downloaded to the package store on an as-needed basis.
This allows a user to download only a small part of the package, typically enough to launch the package and run normal tasks. All other blocks are downloaded when a user initiates an operation that requires data not currently in the package store.
App-V Packages require updating throughout the lifecycle of the application. The upgrade operation is optimized by creating hard links to identical and streamed files from other versions of the same package.
The App-V Client's behavior when packages are removed depends on the package removal method. Using an App-V full infrastructure to unpublish the application, the user catalog files machine catalog for globally published applications are removed, but the package store location and COW locations remain.
Neither operation will remove the Package Store package files. App-V is able to provide a near-native experience when roaming, depending on how the application being used is written. By default, App-V roams AppData that is stored in the roaming location, based on the roaming configuration of the operating system.
Other locations for storage of file-based data do not roam from computer to computer, since they are in locations that are not roamed. The following table shows local and roaming locations when folder redirection has not been implemented. The current App-V Client VFS driver can't write to network locations, so the App-V Client detects the presence of folder redirection and copies the data on the local drive during publishing and when the virtual environment starts.
After the user closes the App-V application and the App-V Client closes the virtual environment, the local storage of the VFS AppData is copied back to the network, enabling roaming to additional machines, where the process will be repeated. Here's what happens during the process:.
However, the data stored in this new location is not roamed with folder redirection. All changes during the running of the application happen to the local AppData location and must be copied to the redirected location. The process does the following things:. The only other condition that must be addressed is a package repair operation. This process will recreate both the local and network locations for AppData and remove the registry record of the time stamp.
In an App-V Full Infrastructure, after applications are sequenced they are managed and published to users or computers through the App-V Management and Publishing servers. This section details the operations that occur during the common App-V application lifecycle operations Add, publishing, launch, upgrade, and removal and the file and registry locations that are changed and modified from the App-V Client perspective.
This document focuses on App-V Full Infrastructure solutions. The App-V application lifecycle tasks are triggered at user sign in default , machine startup, or as background timed operations.
The settings for the App-V Client operations, including Publishing Servers, refresh intervals, package script enablement, and others, are configured after the client is enabled with Windows PowerShell commands. The publishing refresh process comprises several smaller operations that are performed on the App-V Client. Since App-V is an application virtualization technology and not a task scheduling technology, the Windows Task Scheduler is utilized to enable the process when the user signs in, the machine turns on, and at scheduled intervals.
The client configuration during setup listed in the previous section is the preferred method when distributing the client to a large group of computers with the correct settings. These client settings can be configured with the following Windows PowerShell cmdlets:. Adding an App-V package to the client is the first step of the publishing refresh process. The end result is the same as the Add-AppVClientPackage cmdlet in Windows PowerShell, except the publishing refresh add process contacts the configured publishing server and passes a high-level list of applications back to the client to pull more detailed information, rather than just doing a single package add operation.
The process then configures the client for package or connection group additions or updates, then accesses the appv file. Next, the contents of the appv file are expanded and placed on the local operating system in the appropriate locations.
The following is a detailed workflow of the process, assuming the package is configured for Fault Streaming. The Publishing refresh process supports targeting machines or users. The App-V Publishing Server uses the identity of the initiating target, user or machine, and queries the database for a list of entitled applications.
The list of applications is provided as an XML response, which the client uses to send additional requests to the server for more information on a per-package basis. The Publishing Agent on the App-V Client will evaluate any connection groups that are unpublished or disabled, since package version updates that are part of the connection group cannot be processed. Configure the packages by identifying the Add or Update operations.
The package file is opened and the AppXManifest. Completely stream publishing block data defined in the StreamMap. All other files are created when the directory is listed as sparse on disk and streamed on demand. Create the machine catalog entries. Create the Manifest. Create the Registry. Invoke scripting from the AppxManifest. This will not perform a package deletion but rather remove integration points for the specific target user or machine and remove user catalog files machine catalog files for globally published.
Packages that already have publishing information for the machine or user are immediately restored. This condition occurs as a product of removal without unpublishing with background addition of the package. This completes an App-V package add for the publishing refresh process.
The next step is publishing the package to a specific target machine or user. During the Publishing Refresh operation, the specific publishing operation, Publish-AppVClientPackage , adds entries to the user catalog, maps entitlement to the user, identifies the local store, and finishes by completing any integration steps. User targeted packages: the UserDeploymentConfiguration. Machine targeted global packages: the UserDeploymentConfiguration.
For connection groups, the path that stores the specific catalog information includes PackageGroups as a child of the Catalog Directory. Review the Machine and User Catalog information in the preceding sections for details.
After the Publishing Refresh process, the user launches and then relaunches an App-V application. The App-V Client checks the path to the user catalog for files created during publishing. After establishing rights to launch the package, the App-V Client creates a virtual environment, begins streaming any necessary data, and applies the appropriate manifest and deployment configuration files during virtual environment creation.
Once the virtual environment created and configured for the specific package and application, the application starts. This might seem like a lot, but the process in action is actually quite fast, and is optimized to minimize network traffic.
If the files are present, the application is entitled for that specific user and the application will start the process for launch.
There is no network traffic at this point. Next, the App-V Client checks that the path for the package registered for the App-V Client service is found in the registry. Upon finding the path to the package store, the virtual environment is created. If this is the first launch, the Primary Feature Block downloads if present. After downloading, the App-V Client service consumes the manifest and deployment configuration files to configure the virtual environment and all App-V subsystems are loaded.
The Application launches. For any missing files in the package store sparse files , App-V will stream fault the files on an as-needed basis. The current version of App-V's package upgrade process differs from the older versions in its storage optimization. App-V supports multiple versions of the same package on a machine entitled to different users. Package versions can be added at any time, as the package store and catalogs are updated with the new resources.
During an upgrade in the new version, only new files are added to the new version store location, and hard links are created for unchanged files. This reduces overall storage by only presenting the file on one disk location, then projecting it into all folders with a file location entry on the disk.
The extension points are switched to the Version 2 location in machine or user catalogs for any newer or updated extension points. If you try to upgrade a package that is currently in use, the upgrade task is placed in a pending state. The upgrade will run later, according to the following rules:. When a task is placed in a pending state, the App-V Client also generates a registry key for the pending task, as follows:.
The following operations must be completed before users can use the newer version of the package:. App-V Packages can be published in one of two ways; as user, which entitles an App-V package to a specific user or group of users, or as global, which entitles the App-V package to the entire machine for all users of the machine. Once a package upgrade has been pended and the App-V package is not in use, consider the two types of publishing:. Removing App-V applications in a Full Infrastructure is an unpublish operation and does not perform a package removal.
