I disabled the anti virus and I can't find the preferences> spotlight in CS4 to add the folder. However in the preferences it says output for the default folder. I am using PC not MAC... I tried it like a hundred times but it doesn't seem to work!
I'm not clear what you are really saying. It would realyl help if you provided screenshots or exactly tell us your steps, in particular to which location you are trying to save. The basic gist of the error message is that there is a permission problem which prevents the program from overwriting an existing file, but why and how is unclear. Could even be something with your temp directory. Impossible to tell at this point.
The problem is very simple. I try to export the video as .swf but sometimes it give me the above message with an incomplete video or it does not give me this message and still end up with an incomplete video.
I tried to disable the anti virus but it still didn't work.
I am not sure why it ends up like this.
The error is not listed on the link you provided and I can't find the solution in any of the forums. I am sure there is a solution, but I just don't know it. .
