Now available for download: Hotfix Package 3 for Microsoft Application Virtualization 4.6 Service Pack 1: July 2011

This hotfix package resolves the following issues:

You run the Application Virtualization Client on a computer that is running Windows XP or Windows Server 2003. When you try to start a virtualized application from a network location, such as a UNC path or a mapped network drive, you receive an application error message that states that a .dll file could not be found.
When you try to run an Open Software Description (OSD) file that contains a batch script from a content share, you receive a "04-00000020" error message.
The Application Virtualization Client service may take a long time to start and may result in slow startup performance in certain computer configurations.
The Save As New Package option of the Application Virtualization Sequencer does not correctly update the virtual registry.
When a virtualized application calls the Windows API LoadLibrary function, the application does not work correctly in the App-V 4.6 SP1 Sequencer. This issue occurs only when the LoadLibrary function uses a parameter that has a trailing period (.) at the end of the module name.
