Starting with version 2603, Citrix Workspace app for Windows is available as a native 64-bit (x64) application and is now generally available (GA). The x64 build removes 32-bit constraints affecting graphics performance, clipboard handling, and security integration. During the dual-support transition window, both 32-bit and 64-bit installers are provided an updated x64 Virtual Channel SDK is available for migrating custom virtual channels. For more information, see Transition to 64-bit Architecture — FAQ article.nnThe approach is to create a common registry key to identify which installer (32bitor 64bit) is installed on the machine, and then add this as a rule.
