When trying to install XenApp 6 from the command line using the XenAppSetupConsole.exe options_properties, it fails with the following error message.
"Citrix extensible Meta Installer has stopped working."
After following [#227578] in the Readme for XenApp for Windows Server 2008 R2, continued troubleshooting found the following output in the command window.
