There are two possibilities to update the version of the software: first open Pro Shop Coordinator Plus interface, go to About window and hit the Check for updates button. If the download process doesn't start, then I suggest you to perform a fresh installation of this software. Go to Control Panel > Uninstall a program > search Pro Shop Coordinator Plus and hit uninstall. After that download the latest version from its official webpage. After the download is complete, open the setup file and start the installation process once again.
