This article describes a hotfix package for July 2009 that
contains the latest hotfixes for Microsoft Application Virtualization 4.5
Cumulative Update 1 (App-V 4.5 CU1).
Note We recommend that you test hotfixes before you deploy them in a
production environment. Because the builds are cumulative, each new hotfix
release contains all the hotfixes and all the security fixes that were included
with the previous update package. We recommend that you consider applying the
most recent fix release that contains the most necessary hotfixes.
hotfix package addresses the following issues:
When you apply a disk quota to the profile directories
of an user and when the disk quota is near the limit, the App-V client leaks paged pool
When run as a virtual application, a process that calls
RegQueryMultipleValues experience unexpected errors or cannot start. For
example, you receive error messages when you start or shutdown the Trapeze application
and the application does not work correctly.
When a App-V client tries to perform a publishing refresh
procedure over HTTP or HTTPS, the procedureis not completed successfully. Specifically, the
procedure is not completed successfully if a package contains
pathnames that have Japanese characters. This problem occurs when the App-V
client is running a Japanese version of Windows XP and has Internet Explorer 6
When run as a virtual application, Microsoft Access 97
generates an error message 1008 when Access 97 is moving temporary files.
When a Microsoft Application Virtualization 4.5 client
tries to perform a publishing refresh procedure over HTTP or over HTTPS on an IPv6
network, the procedure is not completed successfully.
When you expand a %APPDATA% environment variable to a
universal naming conventions (UNC) path, application-specific failures occur when you start virtual applications.
In environments that have a trust relationship and mapped
user accounts between a Windows Domain and an MIT Kerberos realm, the Microsoft
Application Virtualization 4.5 client cannot log on to a publishing server.
Additionally, you receive an error message 8009030C.

With this fix enabled, Microsoft Application Virtualization
4.5 does not correctly publish an application after a publishing refresh when
you add or remove a user from an Active Directory security group that is used
to control access to an application. The user has to log off and then log back
on to see the changes.
Running Microsoft Application Virtualization 4.5 in
environments that have a trust relationship and a mapped user account between
Windows Domain and MIT Kerberos realm is not supported by this hotfix. In some
environments, installing this hotfix may enable this configuration to work.
However, this configuration in these environments will not be supported until a
future release of Microsoft Application Virtualization 4.5.
