I have installed Acrobat Pro (latest version) and LiveCycle ES2 server. What I've been having trouble with is installing LiveCycle ES2 Service Pack 2 (SP2). The error using the default folder reads:
Invalid Install Folder
You are attempting to apply Adobe LiveCycle ES2 Service Pack, SP2, to a folder (C:\Adobe\Adobe LiveCycle ES2) which doesn't contain Adobe LiveCycle ES2 Server.
Click Back to Select a different path or Cancel to terminate the patch installation.
Even after I have tried choosing the folder that contains the FornDesigner.exe program, I received the same error message.
