# Getting Started Know your browser! MiVoice Office 400 CCS is a suite of single page applications that run within your browser. The apps have been tried and tested in the latest versions of Internet Explorer, Google Chrome, and Mozilla Firefox (2015). Other browsers are available, but the apps may not work in older browsers, specifically those that do not support HTML5 and CORS. For instance, any version of IE before v9 does not support CORS so cannot be used to run the apps. We recommend that before you start using the CCS apps you update your chosen browser to the latest available version. Single page application just means that when using the app you do not need to navigate between pages in your browser, like you would on a web site for instance. If you have used an EXE program in Windows before you know how a single page application works, it's just like a EXE program. Load the app by entering the required URL in the browser address bar and you won't need to navigate away from that address or open new tabs or windows, the application does it all for you. You'll need to know either the COMPUTERNAME or the IP address of the PC that has the CCS Web Server installed on it, as well as the port number the Web Server been configured to use. Ask your network administrator for this information before proceeding. Read Finding the Apps for details of how to find the various Apps from the browser. Remember that just closing the browser or navigating to a new page is not the same as logging out of a CCS app. Read Logging in and out to find out why logging out is so important and remember the option for Revoking licenses if you suddenly find that you can't open as many instances of an App as your CCS License allows. We have an FAQ and a Troubleshooting section which you may find useful if things don't go as you expect.
