To those who are having issues getting the Embedded Client to work on ESXi 5.5 the following has worked flawlessly for me on numerous hosts so far :
1) ssh into host (assuming you have ssh enabled)
2) Install the embedded host client
esxcli software vib install -v http://download3.vmware.com/software/vmw-tools/esxui/esxui-signed.vib
3) Assuming you have a datastore called DataStore1 copy the endpoints.conf and delete the ui line
cp /etc/vmware/rhttpproxy/endpoints.conf /vmfs/volumes/datastore1/
vi /etc/vmfs/volumes/datastore1/endpoints.conf
bring cursor to ui line and press d twice. :wq to save the file
4) Copy the file back over the original endpoint.conf and restart the rhttpproxy service
cp /vmfs/volumes/datastore1/endpoints.conf /etc/rhttpproxy/
/etc/init.d/rhttpproxy restart
5) You should now be able to browse to the https://IP-Address/ui/
remember that the trailing / on the url is important in 5.5
Hope this helps.
