Even after uninstalling the RSA Authentication Agent 1.0 we get following error in event viewer logs:

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Information
=========
RSA Authentication Agent 1.0 is not compatible with the Storefront version 3.5 and above.
Solutions created for versions of StoreFront before 3.5 will no longer work in SF 3.5 and above because of the StoreFront Authentication SDK update.

Here the MMC crashed even after uninstalling the RSA Authentication Agent.
As per the error we do see RSA.Authentication.CitrixConnector.Console.Extension.dll under C:\Program Files\Citrix\Receiver Storefront\Management, however renaming or removing it also doesn't help.

Solution
========

Under location HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DeliveryServicesManagement\Plugins\Authentication\Extensions 

There would a key called SecureID with RSA.Authentication.CitrixConnector.Console.Extension as the value. 

Remove it and rename its dll under location C:\Program Files\Citrix\Receiver Storefront\Management 
It should work then.
