Hotfix package 6 for Microsoft Application Virtualization 5.0 SP2

This article describes a hotfix for an issue in Microsoft Office Click-to-Run that occurs when the Microsoft Application Virtualization 5.0 (App-V 5.0) Service Pack 2 (SP2) client is installed. Before you install this hotfix, see the Prerequisites section.

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.

Issues that are fixed in this hotfix package

Office Click-to-Run applications do not start when you try to open Office documents from Microsoft SharePoint.

The App-V 5.0 SP2 client tries to virtualize Office Click-to-Run applications. This breaks integration with SharePoint and prevents Office Click-to-Run applications from starting when the user tries to edit Office documents that are hosted on SharePoint sites.

Installation information

If the original client was deployed by using the .msi file, you must apply the .msp file to experience a successful update. To extract the .msp file, run the following command:

AppV5.0SP2-Client-KB2956985.exe /LAYOUT

Important note When you try to uninstall an update, the attempt fails if a just-in-time virtualization (JIT-V) package is being used.

This issue was introduced with the just-in-time-virtualization (JIT-V) feature in App-V 5.0 SP2. All SP2 hotfix (patch-level) releases may experience this issue if the following conditions are true:
  • You installed the client by using a Windows Installer (.msi) file, and then you apply updates by using a Microsoft Installer Patch (.msp) file.
  • You try to uninstall an update by using the Add or Remove Programs item in Control Panel.
  • A JIT-V enabled package is running on the system.

  1. Start Local Services.
  2. Stop the Microsoft App-V Client service.
  3. Uninstall the update by using the Add or Remove Programs item in Control Panel.
  4. Start the Microsoft App-V Client service.
