when I opened the creative cloud tool for updating to CC 2014 and Lr 5.5, I recognized that Lr 5 was mentioned two times. For the 'first Lr', there was a button update which I used to update for 5.5, and next to the second, there was no update abvailable. After updating all apps, both Lr 5 are marked up to date.
Why are there 2 different Icons for the same Lr 5 Version ? To my knowledge, there is only one Lr 5 installed to my machines. Furthermore, I recognized the same on both my PC and my Notebook.
Best wishes and thanks for further answers !

-so do not uninstall the older CC programs if you use plugins in your programs until you are sure you have plugins that work in CC2014
If you are sure you don't need the old CC programs
