When running the XenApp Configuration Wizard you may get the following error.

There are many reasons this may occur but I have noticed it always occurs with the latest version of the licensing server 11.10 whether you have specified the correct Product Type or not. The work around for me was to choose “Select the model at a later time”

This will let you complete the wizard. You can then use Citrix policies to set the license server location, port and model type at which point everything works.
