Released: Hotfix Package 5 for Microsoft Application Virtualization 4.5 Cumulative Update 1: August 2009

  • Artykuł

untitled On Monday I posted a list of app-v versions based on releases that we have shipped. One of them was hotfix rollup 5 which J.C posted on the app-v blog. The hotfix package for August 2009 that contains the latest hotfixes for Microsoft Application Virtualization 4.5 Cumulative Update 1.  This hotfix package addresses the following issues:

  • It takes significantly longer to stream a package over the RTSPS protocol than to stream a package over the RTSP protocol.
  • When you use TrueCrypt for drive encryption, any attempts to mount an encrypted volume may generate a 0xA stop error.
  • The Microsoft Application Virtualization 4.5 client leaks paged pool memory. This problem occurs when you apply a disk quota to the profile directories of a user and when the disk quota is near the limit. .
  • A virtual application that calls the RegQueryMultipleValues function may experience unexpected errors or fail to start. For example, you receive error messages when you start or shutdown the Trapeze application. Then, the application does not work correctly.
  • When an Application Virtualization 4.5 client tries to perform a publishing refresh procedure over HTTP or over HTTPS, the procedure is not completed successfully. Specifically, the procedure is not completed successfully if a package contains pathnames that have Japanese characters. This problem occurs when the Application Virtualization 4.5 client has Windows Internet Explorer 6 installed and runs a Japanese version of Windows XP.
  • When it is run as a virtual application, Microsoft Office Access 97 generates an error message 1008 when Office Access 97 is moving temporary files.
  • When an 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.
  • The Microsoft Application Virtualization 4.5 client cannot log on to a publishing server. This problem occurs in environments that have a trust relationship and a mapped user account between a Windows domain and an MIT Kerberos realm. Additionally, you receive an error message 8009030C.
    Note You can resolve this problem by creating a UseMITKerberos registry value.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

  1. Start Registry Editor.

  2. Locate and then click the following key in the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Client\Network

Important

  • Consider the following scenario. You add or remove a user from an Active Directory security group that is used to control access to an application. Then you enable this hotfix. In this scenario, Application Virtualization 4.5 does not correctly publish the application after a publishing refresh procedure. The user must log off and then log back on to see the changes.
  • This hotfix does not support Application Virtualization 4.5 in environments that have a trust relationship and a mapped user account between a Windows domain and an MIT Kerberos realm. In some environments, this configuration may work if you install this hotfix. However, this configuration will not be supported in these environments until a future version of Application Virtualization 4.5 is released.
