Not sure I understand your question.
You asked me to install the update, which I downloaded and just have run for CS5.5.
I want to get 5.5 working so I can use it, but after installing the update or 5.5, 5.5 still won't open.
Current error message is at http://pastebin.com/4JWxLbBT
My question was do I have to do the same update for 3 and 5 that I did for 5.5? If I can get 5.5 working, I only care about 5 if it's a necessary step in the whole process.
