In a domain with hundreds of deployed Win7 boxes with the current Citrix Receiver (v184.108.40.206) we have a small handful of machines that throw the error, "A fatal error occurred. Would you like to restart Citrix Receiver?"
Clicking Yes causes the same error to pop up. Clicking No closes the notification window, and Citrix works ok. Another error my throw within seconds, minutes, or may not show up again for days.
Under Citrix Receiver | About | Advanced | the "Reset Receiver" option did not seem to help.
Ultimately, it doesn't seem like the issue is stopping users from connecting to our Citrix environment via web browser, but something appears wrong and the users are not happy with the sometimes constant errors.
Checking the Application Event Log, Event ID 1 appears. Here is some of the description:
Self-service Plug-in exited unexpectedly. Exception was Object reference not set to an instance of an object. at Dazzle.AppMonitor.Control.Controller.UnhookAuthManagerWindowEvents()
Receiver has been uninstalled, followed by use of the 2014 version of the Receiver Cleaner Utility, with a manual search-and-destroy for registry entries and program files tossed in for good measure.
Google searches on this seem to point to the steps followed above or corrections in coding, but nothing useful for troubleshooting at the client (desktop) end.
Does anyone have familiarity with this?
