SpoonReg is a tool that provides a simple command-line interface for deploying
virtual applications and managing the virtual desktop environment. Users and
administrators can use SpoonReg to register virtual applications for a single user or,
in the case of administrator, a group of users or devices. SpoonReg can be used to
deploy a manage virtual applications and layers built using ZENworks Application
Virtualization.
SpoonReg also provides the ability to create, reset and remove application sandboxes,
virtal environement “bubbles” where the virtualized application resides. Sandbox
management provices fine-granined control over application linking and
intercommunication.
N
O
After virtualizing an application with ZENworks Application Virtualization, it is
often desirable to make the application Start Menu icons, shortcuts and file
associations available on the users’ desktop. SpoonReg allows you to register virtual
applications created with ZENworks Application Virtualization in the shell, creating
all of the shell associations that would generally be created during a standard install
process. Unlike performing an installation, however, registation and un-registration
can be performed almost instantaneously.

Making Applications Portable
Command-line syntax:

AppSpec: An AppSpec is a path (relative or fully qualified) to a virtual
executable or layer built with ZENworks Application Virtualization.

SandboxSpec: A SandboxSpec is the name or path of a virtual sandbox.
Registering a virtual application:
To Register an application, use the command.
SpoonReg.exe AppSpec
This command creates all start menu items, desktop shortcuts, and file associations
associated with the virtual application executable.
By default, registration will create a local cached copy of the virtual application
executable and use the users’ local porfile as the sandbox location.
Advanced Registration Options
N
O
Command-line parameters can be used to control the caching behaviour and sandbox
where the virtual application should be registered:
Version 1
SpoonReg.exe [Options] AppSpec[@SandboxSpec]

Options:
/nocache: The virtual application executable will not be copied to the client
machine. All shortcuts and associations will point to the full path as given by
AppSpec

SandboxSpec: This parameter refers to the name and patch to an existing
sandbox with that name exists, the application will be registered into that
sandbox.

Updating a virtual application
To force an application executable to be updated, use the command:
SpoonReg.exe /update AppSpec[@SandboxSpec]
Running the registration command without the update flag will perfom an update
only if the cached and source versions of the application are different.
Updating registration settings
Application registration settings can be changed by re-executing the registration
command with the desired options:
SpoonReg.exe [Option] AppSpec[@SandboxSpec]

/nocache: Disable caching of the specified application (reverses the /cache
setting)

/cache: Enable caching of the specified application (reverses the /nocache
setting)
Unregistering a virtual application
Unregistering a virtual application reverses the registration process, removing the
virtual application, Start Menu icons, shortcuts, and file associations.
To unregister a virtual application, use the following command:
SpoonReg.exe /unregister AppSpec[@SandboxSpec]
It is also possible to unregister all applications with the single command:
N
O
SpoonReg.exe /unregisterall

Making Applications Portable
The SpoonReg tool allows creation and management of one or more virtual
environment sandboxes.
A sandbox contains all of a virtual application’s isolated data and settings as
determined by the virtual application’s isolation configuration settings. Applications
registered to the same sandbox can view and modify each others’ virtualized data and
settings.
By default, all applications are registered into a single default sandbox named
Default. In some cases, it may be desirable to group related applications into a
sandbox that can be treated as a single management unit. For example, when a
sandbox is reset, all of the application content and data stored in that sandbox is
purged and reverted back to the default state.
Creating a sandbox
If no sandbox is specified during registration, the application will be registered to the
default sandbox (Default). To create an additional sandbox, use one of the following
commands:
N
O
SpoonReg.exe [Profile] /create SandboxName [SandboxPath]
SpoonReg.exe [Profile] /c SandboxName [SandboxPath]
If no path is provided, a default path is created under the AppData folder under the
specified profile.

ATT103-Novell ZENworks Application Virtualization: Making Your Applications Portable / Lecture
Resetting a sandbox reverts all changes made to the sandbox, including any changes
to data or settings made by the user. This restores all applications registered to the
sandbox to thier defualt state. To reset a sandbox, use one of the following commands
SpoonReg.exe [Profile] /reset [SandboxSpec]
SpoonReg.exe [Profile] /r [SandboxSpec]

Deleting a sandbox removes all applications, data, and settings from the sandbox. To
delete a sandbox, use one of the following commands:
SpoonReg.exe [Profile] /delete [SandboxSpec]
SpoonReg.exe [Profile] /d [SandboxSpec]
If a SandboxSpec is not supplied, the default sandbox will be reset (the default
sandbox cannot be deleted) Any application registered to the deleted sandbox will be
moved to the default sandbox.
Moving a sandbox
You can use XReg to move the sandbox location to a given path. To move a sandbox,
use the following comman:
N
O
SpoonReg.exe [Profile] /move SandboxSpec SandboxPath

Other advanced application configuration
Depending on the configured isolation settings, certain edit and write operations may
be redirected by the application virtualization engine into an application sandbox, a
filesystem folder where isolated modifications are persisted. Typically, bthe sandbox
is located in a folder or network share where the user has full read and write
permissions, allowing sandbox contents to be accessed and modified by the end user
without any authentication or UAC prompts.

Sandbox Placement Considerations.
N
O

Version 1
By default, the sandbox is placed in the
@[email protected]\Novell\SANDBOX\@[email protected]\@[email protected]
folder, where the @AP[email protected] token represents the local
Application Data folder, and @[email protected], and @[email protected], represent the
application title, and version, respectively. The application title and version
are configured in the Properties area. This location is the recommended
default location for sandbox contents, as end users have full permissions to
this location on standard Windows configurations. Note that distinct builds
of the same virtual application use distinct sandbox locations by default; you
may want to modify this behavior if persisted user settings should be
preserved between virtual application updates.

If deploying the virtual application on a USB device, place the sandbox in a
subfolder of the @[email protected] directory, which represents the location of the
virtual application executable. This will have the effect of directing writes to
the USB device. The recommended sandbox location for USB deployment
is @[email protected]\Spoon\SANDBOX\@[email protected]\@[email protected]\


When publishing new versions of a virtual application, direct the sandbox to
the same location as the older version if you want user settings and data to be
retained in the new version. Direct the sandbox to a different location
(typically, by rolling the subdirectory version number forward) if you want
user settings and data to be reset.

Environment variables may be referenced within the sandbox location by
enclosing the variable between percent signs, ie %VARIABLE%.

@[email protected]: Product title

@[email protected]: Product publisher

@[email protected]: Full version string, in dotted quad format

@[email protected]: Publisher web site
@[email protected]: Virtual application build time, in a format similar to
2008.02.01T08.00.
Standard root folder variables. From the Settings page, you can also
customize the sandbox location. The following variables can be used in the path:

@[email protected] : Folder where the executing virtual application executable
resides

@[email protected] : The Windows operating system install location root.

@[email protected] : The Program Files folder



10
Generally, you should not place the sandbox under any privileged folders,
such as @[email protected] or @[email protected] The virtual application
may fail to execute properly if the ZENworks Application Virtualization
engine is unable to write to the sandbox location at runtime.
Sandbox Location Variables. In addition to the standard root folder variables, the
sandbox location can contain the following token variables. These variables are
based on the values specified in the Properties area of the Settings pane.


If deploying the virtual application on an intranet file share, place the
sandbox in a user-accessible subfolder on a shared network drive. The
recommended sandbox location for intranet deployment is

The Publis to USB feature publishes virtual applications to USB storage devices.
When the USB storage device is attached to a host system, the virtual application
automatically registers the Setup information to the host shell environment. This
information is automatically unregistered when the USB device is removed from the
host system.
Follow the steps below to deploy virtual applications on USB devices:
1.
Open an existing virtual application configuration.
2.
Attach a USB storage device to the host system.
3.
Click Publish to USB, select the USB storage device, and click Publish.
4.
After the virtual application is published to the USB storage device click OK.
1.
Attach the USB storage device to the host system
2.
(If prompted by AutoPlay, choose the XUsb.exe option. XUsb will then register
the file associations and shortcuts associated with the virtual application.)
3.
Remove the USB storage device to unregister the virtual application from the
host system
