Certain App-V 5.0 Service Pack 1 (SP1) packages do not work with the App-V 5.0 Service Pack 2 (SP2) clients.
This is an issue in App-V 5.0 SP2 that may appear to prevent some applications from starting. This includes packages that were sequenced on earlier versions of App-V 5.0. A valid App-V 5.0 package starts correctly and displays a GUI under App-V 5.0 SP1. Under App-V 5.0 SP2, the same package does not display a GUI, or it appears not to start.
A sharing violation occurs during profile synchronization when you use App-V 5.0.
When an App-V user on a Remote Desktop Services (RDS) server logs on after a period of inactivity, a sharing violation may occur when the profile is synchronized to the local cache. Therefore, some required files are not copied over, or they are renamed. In this situation, the profile becomes corrupted.
App-V client handlers leak in Remote Desktop Services (RDS).
When an RDS user logs off, App-V does not release some handles that it held specifically for this session, and therefore the resource cannot be reused. In this situation, the Session ID monotonically increases without reusing IDs from previously finished sessions.
A virtualized Excel Visual Basic for Applications (VBA) application fails if the path for the application contains Chinese or Japanese characters.
Certain applications don't start after Hotfix Package 1 for APP-V 5.0 Service Pack 2 is applied.
Selected registry key values were removed after the deployment of Hotfix 1 for APP-V 5.0 Service Pack 2. This prevents some applications from starting. By reverting Hotfix Package 1 for APP-V 5.0 SP2, you restore these registry values to their default state. However, any existing customizations will be lost and will have to be redone.
Note This issue only affects deployments that were upgraded from APP-V 5.0 Service Pack 1 to APP-V 5.0 Service Pack 2 before Hotfix Package 1 was applied. Remote Desktop Services (RDS) deployments are not affected by this issue.
