In Windows did you go to Uninstall programs and look for CS6 beta? If you uninstalled it fine, if you just deleted it not so good. But then if you ran the Adobe Script cleaner you should have gotten all the remnants.
Have never used the script cleaner, but understand there are differnt levels of removal one can use.
I looked for it for uninstall program and it is not there. And I've just deleted. I tried everything, I even used the function with the clean "delete all" to make sure there's no single trace of it. No hope.
I don't know what I am supposed to do, I don't find it in the programs in order to uninstall it, I already deleted in the bin (stupidly) and I've cleaned everything with the cleaner. It keeps on puting the same message.
