Today I “launched” a new free tool to provide some organized help with App-V Client errors. This tool, called A Failure To Launch, is a Silverlight app that allows you to search for information on an error code produced by the App-V Client.
For each of the codes covered, the tool provides information about the cause (or possible causes), troubleshooting techniques or recommended actions, and links to Microsoft KB Articles when they exist.
The tool also explains the error code format, and has an interesting flow chart showing the steps that the client and server go through to launch an application with links to the various errors.
Not all client errors are covered, and the flow chart is a “best guess” and is known to be inaccurate on some details. Most of the information in the tool can be found on the web somewhere, but some is not. Some come from painstaking attempts to break the system in ingenious ways, and some come from tips provided to be by friends (a special mention goes out to fellow MVP Nicke Kallen). Ultimately, the tool makes for a convenient first place to look.
I wrote it in Silverlight, specifically because you can install the app on any Silverlight enabled device, and then run the tool offline. To do so, just go to the tool off of the website. When it loads, right click in an open area and select the “install” option for the app. Now you can launch it anytime from your start menu, even disconnected from the Internet!
