This article describes how to enable automatic crash dump generation for Microsoft Application Virtualization (App-V) 4.5 and 4.6 clients. This method has the advantage of using functionality already built in to the product, so no additional software is required to be installed. Note that enabling the registry keys below will potentially generate a number of large files in the Dumps folder; carefully monitor servers or desktops where this option has been set for disk usage. This should normally be done under the guidance of a Microsoft Support professional.
