This hotfix package resolves the following issues.
Issue 1: Virtualized Adobe Acrobat running through an App-V Client on Windows 7 crashes or stops responding because of DLL issues
Virtualized Adobe Acrobat running on Windows 7 may crash or stop responding because of an interoperability issue between App-V and Adobe. This issue causes App-V to sometimes load multiple copies of the same DLL from different locations. This, in turn, causes the virtual Adobe Acrobat application to crash or stop responding when certain operations are performed. This issue is fixed in this hotfix package.
Issue 2: Stop error is triggered by DLL issues when an App-V Client tries to load Adobe Acrobat packages
Some products, such as Adobe Acrobat, use DLLs that have file name extensions other than .dll. When an App-V Client loads virtualized packages of these applications, it does not recognize these files as DLLs and does not exclude them from the copy-on-write subsystem. A Stop error may occur when a package is run that uses these DLLs.

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 Service Pack 2 (SP2). All SP2 and SP3 hotfix (patch-level) releases may experience this issue when the following conditions are true:
- You install 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.
To work around this issue, follow these steps:
- Start Local Services.
- Stop the Microsoft App-V Client service.
- Uninstall the update by using the Add or Remove Programs item in Control Panel.
- Start the Microsoft App-V Client service.
