Deinstalling Thingworx - Installer says its still there

I am attempting to clear Thingworx from my VM and reinstall a clean 9.7 version. This is Redhat 9.2 and MSSQL DB (on different host). /opt/ptc folder was moved off. In Root home, .ptc_ccif was moved off and CINC was deinstalled. /opt/cinc has been cleared as well. This is what the bitrock installer shows:

The installer exits since it says a pervious installation of Thingworx was found. How? Where is it determining that? Is there a deinstall step I missed?
