:) :) Hi Lee Jae Guen!
If installation does not work, you can always manually copy the files to the Config folder.
It may be something with the install path on your computer that is confusing it.
Here is an instruction that describes the process for 3.5, but is the same for 4.
CS3 Config folder should be:
Make sure Flash is closed
Just go inside Source_Files in the unzipped EDAPT installation folder and copy the content of the EDAP Tools into the respective CS3 config folders.
(Ignore the Img folder)
Here are a few screen grabs from my CS3 here:
on Windows you only need the Edapt.dll
the .wfx shortcuts
In Tools you only need these 3:
Everything from WindowSWF and XULControls
Just make sure you copy all the files where they should go and this should work.
Hope this helps!
Let me know how it went :)
