How can I uninstall apps (not extensions)?

2

I'm not sure why you would be trying to use the CCleaner Browser to uninstall apps?

Use CCleaner itself - Tools>Uninstall. 

(Or use Windows  - Settings>Apps )

I am talking about Chrome apps.

Sorry but that is still not clear.

Can you explain exactly what you are wanting to do?
