I must use Firefox 3.6.18 because my college claims it is the only browser compatible with their version of Bannerweb software. I dl'd Firefox from the link they gave me, http://filehippo.com/download_firefox/download/0a12ac3c44501912fff7cc544421ae7c/ When running the .exe file, I immediately get a dialog box with the message, " You may not have the necessary permissions to use all the features of the program you are about to run. You may run this program as a different user or continue to run the program as the current user." Below this text are two radio buttons, one for selecting my current user acount, on which I do have administrator privileges, or the built-in account called 'Administrator', which of course I do not have the password for (it asks for the password). When I select my account and click ok, the dialog box disappears and the setup closes. I am using Win 7 x64. I would appreciate help with this problem or a link to a working copy of 3.6.18.
