It was previously stated in another thread, cmnd center has no option to change install directory, and it didn't recognize my previous sonar installations.
I downloaded the platinum installer manually, (firefox did generate a link), but Cmnd Center has no uninstall option, and there isn't one in windows control panel uninstall menu, or in the platinum install directory on C drive.
Rebooted, restarted Cmnd center, etc... still no uninstall.
Win7 64
How can I uninstall platinum so that it can be reinstalled in the proper directory manually?
I'm missing something.

You can uninstall by right-clicking platinum in the ccc. It also allows you to roll back to a previous version. 

Yep ... always missing the one thing I didn't try lol.
 
Thanks Swamptooth!
