App-V is an application virtualization and application streaming solution from Microsoft. It is a key component to a complete desktop virtualization strategy, and allows flexibility to deliver, test and manage the user settings and applications more easily. The difference between an application virtualization solution and a standard terminal implementation, which makes Microsoft App-V a preferred option, is that applications served through App-V can be cached locally so that customers can continue using them if the connection to the virtual machine is gone.

Application virtualization helps to remove all conflicts between applications, eradicates the need to install those applications on PCs and laptops, supports multiple versions of an application to coexist on the same machine and provides a quicker, less invasive way to deliver and update applications on demand.

Coming on to the App-V client, it is one of the most important pieces of the overall App-V infrastructure, and there are broadly two effective ways that can troubleshoot the local App-V client problems effectively, as mentioned below:

Content Storage

The App-V client uses many locations to store important data, the most common being, local computer directories and registries. This allows the Application virtualization client to put all the data together to give the appearance of a locally installed application to the user. If the administrator understands where the data exactly exists, it can help in troubleshooting problems effectively whenever they come up.

Windows Events

Local Windows Event log is another effective way of troubleshooting App-V client problems. Whether it is for alerting on security, or searching for various event IDs to determine the health of Windows systems, App-V Windows events can do it all. When the App-V client logs information in the local Windows Event log, it records three types of events that greatly help in troubleshooting problems, namely,

• Admin: Records any general warnings and errors.
• Operational: Records the usage of the individual App-V workings.
• Virtual Application: Records the real application launches.
