Issue: After updating the Citrix Workspace App, the ThinPrint Client Windows for ICA does not start anymore so session printers don't get redirected.
Cause: The ThinPrint Client Windows for ICA is not started actively but gets passively loaded by the Citrix Workspace App. Upon installation, the ThinPrint Client automatically creates references within registry keys owned and managed by Citrix. Some Citrix Workspace App updates delete these registry entries, so the ThinPrint Client no longer gets loaded when a Citrix session is initiated.
Solution: Perform a repair or a re-installation of the ThinPrint Client.
