XBAP application failing on second browing domain

Question

I deployed an XBAP application on two different servers with different domain names. Unfortunately, It loads ok on first browsing domain and throws the exception below when browsing second. If I use mage -cc to clear the cache, again, it loads fine on first browsing domain and throws exception on second.

ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. An exception occurred while downloading the application. Following failure messages were detected:

Unable to install this application because an application with the same identity is already installed. To install this application, either modify the manifest version for this application or uninstall the preexisting application.

Answer 1

In the Manifest file, change the version of the application identity or republish, check in the project properties ->publish->check automatically increment revision with each publish. Then publish it and then run it.
