I noticed that Remote Desktop Services Team has posted a new App-V related script to Microsoft TechNet Script Center.

This script is mainly meant for running locally installed apps inside App-V’s virtual environment – without sequencing them – in order to quickly fix certain compatibility problems that App-V’s VE can make go away (like, for instance,  registry change conflicts). This in no way  means that application being run this way is truly virtualized application and that it couldn’t in any way conflict with other locally present applications.

To do its “magic”, script utilizes one lesser known feature in App-V Client, first introduced in 4.5 version, making it possible to specify alternative executable which is launched instead of file pointed by OSD’s FILENAME attribute.

It should be noted that the script requires that Default App-V Application (DefaultApp.osd) has been published to a client as script uses that OSD as virtual environment for application.
