Core5 Desktop Edition for Windows is a stand-alone application and can be run by launching the Core5.exe file included in the product bundle.
We recommend pinning the Core5 FileMaker application to your Windows taskbar to easily launch again.
If you will be using QuickBooks with Core5, the FM Books Connector plug-in will need to be installed. You will have the option to install a demo version of the plug-in during the initial setup. If you wish to install and register the plug-in at a later time, you can do so in the Core5 preferences. See "How do I setup QuickBooks with Core5?" for more details.
