Novell ZENWORKS APPLICATION VIRTUALIZATION 8.0.1 - 8-20-2010 User Manual page 38

4.4.8 Read-only virtual environments
In some scenarios, it may be desirable to prevent the user from making any modifications to the
virtual environment, including the virtual filesystem and registry.
To block all modifications to the virtual environment, check the Virtual environment is read-
only option.
4.4.9 Automatic sandbox reset
The sandbox can optionally be configured to be reset automatically on application shutdown. An
application publisher may want to do this to assure that any changes made to an application's
settings are reverted when the application closes.
To enable the automatic sandbox reset feature, check the Delete sandbox on application
shutdown option.
4.4.10 Compress Payload
Both the application profiling and streaming processes require that packages be built
uncompressed.
To build applications without compression, leave the Compress Payload option unchecked.
4.4.11 Startup executable optimization
The Enable startup executable optimization option attempts to launch the startup executable
within the initial virtual machine process. This prevents the creation of a separate application
process but may be incompatible with some applications.
4.4.12 ZAV command-line arguments
ZENworks Application Virtualization supports command-line arguments of the form /x[arg]
which modify virtual application behavior at run-time. In rare instances, these arguments may
collide with command-line arguments designed for use by the virtualized application.
To disable processing of these arguments, uncheck the Enable ZAV command-line arguments
option.
4.4.13 Window class isolation
The Enable window class isolation option prevents the virtualized application from viewing
window classes that have been registered by external processes. For example, this option may be
used to prevent interaction between virtualized and non-virtualized versions of the same
application when the application checks for existing class registrations.
4.4.14 Enhanced DEP compatibility for legacy applications
The Enhanced DEP compatibility for legacy applications option provides compatibility for
systems with Data Execution Protection (DEP) enabled. This configuration option is used
primarily for virtual applications running on Windows 2003.
4.4.15 Internet Explorer 6 emulation mode
