Same issue here ...
I just loaded all extension took a long time and activating one by one. Now I have this issue:
Unable to open script file “C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\Configuration\Shared\WebAssist\RichTextEditor\iRiteShared.js” (error 3)."
I think it should be more efficient way to do this installation and activation if you bought the entire suite.
Now what to do?
So far I am wasting my valuable time instead of using these tools, which post to work for the get-go.
Let me know what to do.
