Altiris Software Virtualization Solution 2.1

Improvements for this release include the following new features:
Performance Enhancements
Redesigned registry handling yields significantly higher performance and scalability over SVS 2.0.
Support for Microsoft Windows Vista
This version of the SVS Agent can be run on computers using Microsoft Windows Vista 32 bit.
Note
64 bit operating systems are not supported at this time.
Altiris Task Server SVS Plug-in
An SVS Task-Server Plug-in is included in the installation of Altiris Software Virtualization Solution. The plug-in allows you to leverage the benefits of the Altiris Task Server infrastructure including automation and task sequencing.
SVS Control Panel Applet
An Altiris SVS Control Panel Applet is included as an optional component installed with the Altiris Software Virtualization Agent. It is available from the Windows Control Panel.
Depending on the installation of either SVS Admin or Virtual Package Editor (installed with Wise Package Studio) you can use the applet to create, import, export and manage virtual layers, and also configure local software virtualization options. The ability to import multiple archive files has been added. You can also add, edit, and delete Global Exclude entries as well. For more information, see the Altiris SVS Applet chapter in the Altiris® Software Virtualization Solution™ Reference Guide.Note The SVS Admin utility is still included and supported in this release.
Global Exclude Entries
Global Exclude entry support allows SVS administrators to specify, on a global level, certain file type extensions and directory locations that you do not want to be captured into application layers. This feature includes an additional API, and menu items in SVS Admin and the SVS Control Panel Applet for managing the Global Exclude entries. The SVS installer has also been updated to provide the ability to select or deselect two default global exclude entries; Desktop, and My Documents.
Single Screen Refresh
When activating or deactivating layers from SVS Admin there is now a single screen refresh.
Delete Entry Visibility Enhancements
An additional user interface component has been added to the SVS Admin utility. Now, in addition to file delete entries, registry delete entries are also visible.
Layer Data is Retained on Uninstall
To eliminate risk of data loss, uninstalling the SVS Agent 2.1 does not automatically delete all layers on the computer. However, an MSIexec command line option may be used to force the deletion of layers at uninstall time.
Virtualization of System Path Variable
SVS now fully virtualizes the system path variable. Operation works as expected when layers are activated and deactivated. No manual steps or scripting are required.
A New WMI Provider
There is a new WMI provider with improved functionality. This is an additional provider and the legacy provider will still function with this release. Note: The legacy provider will be deprecated in a future release.
Alternate Import Locations through SVS APIs
The SVS APIs support importing a layer to a location other than the default redirect area.
Additional Language Support
The SVS Agent interface has added support for the following additional languages: Danish,Dutch,Italian, Portuguese, Russian and Swedish
The SVS Solution interface on a Notification Server Environment has added support for the following additional languages: Italian and Portuguese
