Launching a virtual application fails with error code 0x41E04304-00000028

Applies to: Microsoft Application Virtualization 5.0 for Remote Desktop ServicesApplication Virtualization 5.0 for Windows Desktops

Symptoms


When a user attempts to launch an application virtualized with Microsoft Application Virtualization (App-V), the application fails with the following error:

The application failed to launch.
This may be due to a network failure.
Error code: 0x41E04304-00000028

Cause


This can occur if the user attempts to launch a virtual application executable from an unpublished package version. This is by design.

Resolution


To prevent this issue from occurring, always launch virtual applications from extension points (e.g., shortcuts and File Type Associations or FTAs).

More Information


When a package version is unpublished, the extension points are removed and the executables in the package version cannot be launched. When a new package version is published, extension points are updated to launch from the most recently published package version. Accordingly, virtual applications should always be launched from extension points, never directly from an executable within a particular package version.
