Citrix Universal DLL Injection Driver Error

Website Visitors:


When users click on the app, it loads the receiver, starts the dialog box which says loading profile, scripts, getting ready etc and the progress bar completes. Just before the application launch, it disappears. Session is created on the server but application wont launch on user’s device.


The Citrix Universal DLL injection driver has encountered an unexpected error.

Event id: 1005 on the app server(VDA server).


Restarting the app server will temporarily fix the issue. Root cause is, trend micro on the app server. In the trend console, look for the errors and processes that are blocked in trend, for that server and whitelist them. You can also temporarily unmanage (remove from trend temporarily) that app server from trend and check the issue.
