MDOP 2013 embeds APP-V MSI’s inside of EXE files
If you are looking for the MSI installer files for APP-V 5 SP1, you will need to manually extract them from the EXE files. The App-V 5.0 SP1 (Client/Server) MSI’s can be extracted using this command:
appv_xxx_setup.exe /Layout /LayoutDir=”<path>”
c:temp>appv_client_setup.exe /Layout /LayoutDir=”c:temp”)
The language pack MSI will be laid out with the client or server MSI in the location/path specified in /LayoutDir.
This command is documented here http://technet.microsoft.com/en-us/library/dn144770.aspx.
