I have been attempting to install the trial version of Illustrator CS4 for a couple of hours. It is telling me that it cannot install until I close all open programs, namely Adobe Bridge. Adobe Bridge is not open and I even restarted my computer to make sure of this. However, it is still saying that installation cannot continue until Adobe Bridge is closed. Has anybody had this problem? What do I do?
You may try to use the CS4 CleanScript, http://www.adobe.com/support/contact/cs4clean.html.
You may try to run the installation in safe mode, if applicable.
If you still get the error, you may consider taking a turn with the CS3 installation, if any; it has its own CS3 CleanScript., http://www.adobe.com/support/contact/cs3clean.html.
You have the Bridge Quick Launcher active in your tray icons. Terminate it, then run the install.
