Releases Page
Before you distribute a virtual software archive file (.VSA) to end users, you can create a
release for the archive file. A release consists of a WiseScript .EXE wrapper that contains
the logic that is needed to install your application properly.
You use the Releases page in Virtual Package Editor to create a release for a .VSA file.
You can create any number of releases, but normally you would create a single release
for an archive file.
Before you use the Releases page, you should be familiar with the following:
z
WiseScript project file (.WSE)
When you create a release for a .VSA file, a WiseScript project file (.WSE) is
created, which when compiled creates the .EXE wrapper. The .WSE file contains the
logic needed to install the .VSA file. You can edit this .WSE file from the Releases
page.
See
Editing an Archive File’s WiseScript Wrapper
on page 36.
By default, the .WSE file includes installation error messages and several installation
dialog boxes that appear when the end user runs the .EXE. It also includes the
installation’s maintenance mode dialogs that appear when the end user clicks the
application’s Change/Remove button in Add/Remove Programs.

Execution of the .EXE wrapper
When an end user runs the default WiseScript .EXE wrapper, the .EXE wrapper does
the following on their computer:
Determines whether the .VSA file has already been imported into an SVS layer
on the computer. If a .VSA file with the same GUID already exists, a message
informs the end user and the installation ends.
Displays installation dialogs.
Determines whether a compatible version of the SVS Driver (Software
Virtualization Agent) is installed.
If a compatible version of the SVS Driver is not found, the .EXE wrapper
displays an error message and the installation ends.
Creates an SVS layer for the .VSA file and imports the .VSA file into the layer.
Activates the virtual software layer.
Displays a Finish dialog.
