OCLS Toolbar Help

Due to the number of different operating systems and ways in which computers are configured we cannot guarantee that the OCLS Toolbar will install properly. At this point the only browsers that support the toolbar are Microsoft Explorer and very low versions of Firefox (3.5 and lower). The OCLS toolbar does not install on current versions of FireFox nor in any version of Chrome, Opera, or Safari. Some security software also blocks installation of the OCLS toolbar. If the OCLS Toolbar cannot be installed for any reason, similar functionality can be obtained by creating a bookmark (favorite) to the OCLS homepage http://www2.indwes.edu/ocls -- all of the toolbar resources can be found by following links from this homepage.

Many problems can be solved by uninstalling and reinstalling the toolbar.

Known problems are covered below. For others please contact OCLS at 800-521-1848 or ocls@indwes.edu

Installing the OCLS Toolbar on a Mac or Linux computer

Since only very low versions of Firefox support the toolbar it is recommended that the toolbar not be installed on a Mac. Complete access to all OCLS resources is available from the OCLS homepage, http://www2.indwes.edu/ocls.
