Introducing Wise Virtual Package Editor
When you use a data layer, the data is stored separately and is not deleted because
a data layer cannot be reset.
z
Provide a single, portable data store
Data layers can provide a single source of user data files that can easily be exported
to a virtual software archive file (.VSA) and moved or copied to a different computer.
Example: You could create a data layer to store a company’s product catalog and
price list that is updated monthly. Each month, that layer could be exported to a
.VSA and distributed to the sales force to ensure they have the current files. The
layer could then be deleted at the end of each month to ensure that obsolete data is
not circulated or available.

About Sublayers
On the Files, Registry, and Delete Entries pages of Virtual Package Editor, a sublayer
drop-down list appears. Before you select entries on these pages, select the sublayer to
which you want to add the entries. On the Files and Registry pages, you can move items
from one sublayer to the other by right-clicking the file or registry value and selecting
Move to layer.
An SVS layer has the following sublayers:
Warning
When you create a VSP, be sure to set exclusions on the Exclusions page in Virtual
Package Editor. Exclusions prevent the loss of user data when a layer is reset.
See
Exclusions Page
on page 29.
Example: Suppose you create a layer for Firefox. As a user uses Firefox, they may make
some changes to the program. They may select a unique home page, add bookmarks, or
change the original security settings. By default, these user changes are stored in the
Read-only
The read-only sublayer contains all the files and settings
that are not reset when the layer is reset. When you use
SetupCapture to capture an application, everything that is
captured is put in the read-only layer. When you create a
Virtual Software Package (VSP) using the Installation
Expert pages, you normally add files, registry keys, and
delete entries to the read-only sublayer. When a damaged
application is reset, any files or settings from the read-only
layer are restored.
Writable
The writable sublayer contains any files or settings that are
added or changed by a user of a layer. When a layer is
reset, any data in the writable layer is deleted. In Virtual
Package Editor, you use this sublayer mainly for modifying
user specific settings, troubleshooting, or testing.
(Example: When testing a layer, you could add a .DLL to
the writable layer and then simply reset the layer to
remove it.)
