You most likely got the unable to locate file because you uninstalled the main component first...
Now when I had CA I remember that there was a delay between the setup splash screen and the actual installation part of it... did you give it some time after the splash screen started?
I get a message that setup is already running
It probably is happening because the setup process is still running
Restarting your computer might help fix this.
If your comfortable with attempting to use System Restore
to replace the CA installation back to before anything was uninstalled then that is what I recommend trying...if your not that comfortable but you still want to try using System Restore them we can guide you through the process as it is fairly simple
Btu if none of the suggestions work here then personally I would try the CA forums - You can find the CA forums via this link
