A machine SID mismatch would be extremely unusual to say the least.
Did you recently upgrade your OS or copy in the install without running the installer?
Look in c:\programdata\stardock as it may be located under there.
As an additional point it is not recommended to install any of the Stardock products outside of program files. Doing so with CursorFX for example will probably prevent it being able to show the cursor on top of the fullscreen start menu in Windows 8 as security in the OS prevents apps outside of program files from being able to have higher access rights.
