Jeff,
When you install the run-time engine 6.0.2, do you still see the run-time engine 6.0.1 in the add/remove programs? If so, then go and delete the run-time engine 6.0.1 folder from the installation (Shared) directory.
If you installed the run-time engine 6.0.1 with LabVIEW 6.0.1 update, try running the LabVIEW uninstaller, and select to uninstall just the run-time engine.
I hope this helps.
