Hello it's quite a bit later then this original post, but I was having trouble with Creative Cloud launching on Windows 8. But your suggestion helped in part. For me, it seems the app was launching but somehow the task bar icon was disappearing. When I followed this instruction: "go to the Windows Notification Area (aka System Tray), click Show Hidden Icons button, then select the Creative Cloud icon..." selecting the hidden Creative Cloud icon revealed the app was launched but the icon was hidden.
branched to new discussion as the original post was very old
