This article describes Microsoft Application Virtualization 4.5 Cumulative Update 1 (App-V 4.5 CU1). This package provides the latest updates to Microsoft Application Virtualization 4.5.


This cumulative update contains the following changes:
  • Support for Windows 7 Beta and Windows Server 2008 R2 Beta
    App-V 4.5 CU1 addresses compatibility issues with Windows 7 Beta and Windows Server 2008 R2 Beta. Support will be provided for blocking issues that prevent App-V 4.5 CU1 from running in a test environment on pre-RTM versions of Windows 7. This change helps make sure that your virtual applications can run successfully in a test environment in which compatibility between App-V 4.5 Client and Windows 7 Beta is required.

    Note Running App-V 4.5 CU1 on any version of Windows 7 or Windows Server 2008 R2 in a live operating environment is not supported.
  • Improved support for sequencing the Microsoft .NET Framework
    App-V 4.5 CU1 addresses previous issues with sequencing the .NET Framework 3.5 and earlier versions on Windows XP Service Pack 2 (SP2) and later versions.

  • Customer feedback and hotfix rollup
    App-V 4.5 CU1 also includes a rollup of fixes to address issues that have been found in the App-V 4.5 RTM release. This cumulative update includes a combination of known issues and customer feedback from our internal teams, partners, and customers who are using App-V 4.5.
  • In addition to stability improvements, this update addresses the following issues:
    • When you try to set the default value of a registry key by using the REGVALUE OSD element, you receive an error that the OSD file is formatted incorrectly.
    • When you try to open a small application package that has been compressed, it may not start, and you may receive a "0A-00000163" error. Typically, the application package is less than 1 megabyte (MB).
    • When you open a 16-bit application, you cannot access files in the virtual file system. This causes a start failure.
