Hey all.  This is just a quick post to go through an issue that I came across with Citrix XenApp 7.6.  When launching an application the user is prompted with “Running Security Scan” message

And eventually you will be prompted with a message to Open the ICA File which has been downloaded

Obviously this is not a nice experience for the end user.  The issue is occurring due to the enhanced security on IE11. 

Luckily the fix is nice and simple, just add the URL used to access the StoreFront site to the Trusted Sites list and then it will work as expected.
