Hi,

When I try to install Flash Player 9 for OSX I get the following error message:

[b]"It appears that a browser is still running on your system. Please close
all browsers and click 'Continue'"[/b]

I do not have any browsers running, and have tried restarting. I am on an
Imac running OSX 10.4.8.

I have read this tech note http://www.adobe.com/go/4aa64290, but it does not
help me because I am not using the [b]Fast user switching[/b] option.

I'm not experienced with Mac OSX but can you try to run a process listing
software and check if any process that might be a browser is actually running?
Something might be calling the browser on boot...
