an error message tells me to close Bridge CS5 but it's not running!
Yes, it is. Check your task manager and terminate the process.
I know what you are saying but when I go to the menu what do I do? Highlight it and then click end process? When I go to applications the only thing that shows running is the AI assistant and task manager. When I do the end process thing a warning message comes up telling me that I could damage something. Are you sure about this? My photoshop is a purchased product. This is just a trial of illustrator. Please advise asap!
Also should the download take 4 hours before the final install? People I have talked to say they never heard of any trial taking 4 hours.
Four hours sounds like a long time, but it really depends on the size of the file you're downloading and the type of connection you're using. Here are some guidelines to help give you a sense of what's expected:
You might also try disabling startup items, and then restarting your computer and trying the download again to make sure that no programs are running.
I believe this is a duplicate thread for the issue you have posted in http://forums.adobe.com/thread/961889?tstart=0.
As per our conversation earlier today, the issue you were facing has been resolved.
Please let us know in case of further issues with the Illustrator trial.
