Install couchbase-server-enterprise_2.2.0_x86_64.setup hangs, uninstall doesn’t work on couchbase server, repeated installation attempts says cannot upgrade. What’s next MongoDB? It installs fine.
Hello Mike,
Which operating system you are using? Can you give the exact version?
May be you can delete the folders manually (once the process are stopped)
PS: I won’t answer the last question you ask 
Regards
