If you've received error code 40017 when attempting to install Citrix Workspace, this usually signals an issue with the parameters passed to the install command. Double-check your silent install parameters and switches for bad characters or options. Sometimes, a simple typo can be the cause for this otherwise cryptic error message!
Here's an example silent install command for reference, but make sure you revise it as necessary for your situation:
CitrixWorkspaceApp.exe /silent /forceinstall /includeSSON /AutoUpdateCheck=disabled /EnableCEIP=false
